Dixon, initially reported to be joining the team in August, didn’t officially sign on with the C’s until this week. The shooting guard went undrafted out of William & Mary back in June.

Holmes, on the other hand, a big man out of Texas, went undrafted back in 2015 and has struggled with injuries since.

Peak, a familiar face from his time at Georgetown also went undrafted this summer after declaring as an early entrant.

Finally, White, a sharp-shooting swingman inked back in August has also been let go.

Dixon, Peak and White could all end up as affiliate players with with the club’s G League squad while Holmes could end up in Maine as well, with returning rights.

AUGUST 28: The Celtics and rookie swingman L.J. Peak have agreed to a partially guaranteed contract, Adrian Wojnarowski of ESPN tweets. The former Georgetown forward will likely be ticketed to Boston’s G-League affiliate, the Maine Red Claws, Wojnarowski adds.

Undoubtedly, Peak would have to be make a huge impression during training camp to nab a spot on Boston’s opening-night roster. Boston now has 19 players on the roster — 14 with guaranteed deals, three more with partial guarantees and a couple of two-way contracts, as Bobby Marks of ESPN.com notes (Twitter link).

The 6’5” Peak played three seasons with the Hoyas. He averaged 16.3 PPG, 3.8 RPG and 3.5 APG last season as a junior, then went undrafted as an early entrant. He played for the Rockets’ summer-league team and averaged 7.3 PPG in 13.7 MPG in four appearances while making half of his 3-point attempts.

Ranked 46th of DraftExpress.com’s list of top 100 prospects, the junior Hoya will look to stick on a roster seeking to add as many potential weapons as possible. In Peak, the Rockets will get a 21-year-old fresh off a campaign in which he posted 16.3 points and 3.5 assists per game.

Per Chris Haynes of ESPN, the Rockets will also take a flyer on Brazilian point guard George de Paula. An international early entrant in this year’s draft, de Paula comes in at No. 72 on DraftExpress’ big board.

At this time it’s not entirely clear whether the deals will be for Summer League or for training camp, but it sounds like both players should have a spot on Houston’s 20-man camp roster.

Blakely believes that no matter James’ future, Ainge should not focus on what’s going around the league, focusing instead on his own team. The Celtics have the No. 1 overall pick in this year’s NBA Draft and are coming off a year where they were the first seed in the East. The Celtics have their own issues to address, including the impending free agency of Isaiah Thomas, Marcus Smart, and others.

In any case, the Celtics are in the best position of any Eastern Conference team to unseat the Cavaliers as the class of division and a James departure after next season only strengthens that.

Here are other notes from around the Atlantic Division:

• Bobby Marks of The Vertical previewed the Celtics‘ offseason agenda and gave three key points the team should focus on. Marks feels Boston needs to properly allocate its cap space and not be tempted by dealing its first overall pick on a rental player such as Paul George, while being open-minded on the trade market.
• The Raptors announced a two-day free agent camp starting today in which 23 free agents will work out for the team. Some notable names on the list include former Knicks forward Cleanthony Early, former Kings and Rockets forward Tyler Honeycutt, and former NBA D-League player Damien Inglis.
• Cody Taylor of Basketball Insiders (via Twitter) provided a list of players the Nets worked out today, including Jamel Artis, Milton Doyle, Isaac Humphries, Alpha Kaba, L.J. Peak and Sindarius Thornwell.
• The 76ers announced the following players will particpate in a pre-draft workout on Friday morning: Jamel Artis (Pittsburgh); Amida Brimah (Connecticut); Isaac Humphries (Kentucky); London Perrantes (Virginia); Davon Reed (Miami); and Jeremy Senglin (Weber State).

There’s more this morning out of Philadelphia:

• The draft will present Bryan Colangelo with his most difficult decision since becoming the team’s president of basketball operations, writes Keith Pompey of The Philadelphia Inquirer. The Sixers hold the third selection, and there’s no obvious choice if Markelle Fultz and Lonzo Ball are the first two players taken. Duke’s Jayson Tatum would provide much-needed scoring, while Kentucky’s De’Aaron Fox would be a valuable point guard in case the team changes its mind about having Ben Simmons run the offense. Josh Jackson of Kansas and Malik Monk of Kentucky are also considered possibilities. Colangelo said he prefers athletic players with the versatility to handle multiple positions. “If it’s the vision of where we want to take this basketball team, again, talent versus fit is something that we clearly always look at,” he said. “But we’re a young team, the stage where we are. You can’t necessarily choose one or the other. Right now, what we’re looking at is a situation that again the group of players that are available to us at No. 3 is probably going to be able to address both with the same decision.”
• Georgetown guard L.J. Peak, who recently worked out for the Sixers, was a high school teammate of Jahlil Okafor, notes Jessica Camerato of CSNPhilly. They spent a year together at Whitney M. Young Magnet High School in Chicago, and Peak would like to team up again. He is considered a late second-round pick at best, and Philadelphia holds choices No. 36, 39, 46 and 50.
• The Sixers aren’t likely to keep all of their second-rounders, Camerato writes in a separate piece. They already have eight players under contract for next season and will be looking for draft-and-stash opportunities if they can’t unload some of the picks.

There’s more draft news as June 22nd approaches:

• Shooting specialist Luke Kennard of Duke also has a private workout scheduled for the Knicks, Begley adds in the same piece. Kennard may have pushed himself into the top 12 with his performance in pre-draft workouts, including CAA’s event last weekend in Los Angeles, according to Begley, who adds that the Knicks would like to trade for another first-rounder and may be targeting Kennard if that happens. New York has discussed a deal with the Trail Blazers, who hold picks 15, 20 and 26. The Pistons have expressed a willingness to swap the 12th selection for veteran help, and Begley believes the Knicks have reached out to them.
• Kennard is part of a high-profile group to work out for the Pistons today, tweets Keith Langlois of MLive. He is joined by Duke’s Harry Giles, Wake Forest’s John Collins and Kentucky’s Isaac Humphries. Teams are permitted to bring in up to six players at a time, but Detroit is having difficulty getting players to visit because it doesn’t own a second-round pick (Twitter link). Kennard told reporters he has upcoming sessions with the Magic, Knicks, Mavericks and Hornets, who all pick before the Pistons. (Twitter link).
• Ntilikina, Collins and Jarrett Allen of Texas have been added to the list of green room invites for draft night, according to Jonathan Givony of DraftExpress. That brings the total to 13, with more invitations to be extended Monday.
• Creighton’s Justin Patton held his first pre-draft workout this week for the Trail Blazers, tweets Joe Freeman of The Oregonian. He also plans to visit the Nuggets, Pistons, Hornets, Heat and maybe the Thunder.
• Wisconsin’s Bronson Koenig will work out for the Clippers Monday, Begley posts on ESPN Now. He has a session later in the week with the Rockets.
• Georgetown’s L.J. Peak had a workout with the Sixers this week, tweets Jessica Camerato of CSNPhilly. He has future sessions set up with the Hawks, Nets, Knicks, Celtics, Spurs, Wizards and Suns.
• Vanderbilt’s Luke Kornet worked out for the Knicks this week, relays Marc Berman of The New York Post. He also had workouts for the Kings, Celtics, Suns and Jazz.
• Indiana’s James Blackmon Jr. has worked out for the Pistons, Kings, Wizards, Magic and Rockets, with more on the schedule, tweets Alex Kennedy of Hoops Hype.

“It went well. I had dinner with him last night. He had a physical yesterday and he had a workout this morning with Brad [Stevens]. Everything went well. He’s very talented,” Ainge told Himmelsbach by phone Tuesday.

But that is not all going on in the Atlantic division:

• Fresh off the first season of his sizable contract with the Celtics, Al Horford opens up about the high expectations and immense pressures he faces in an article from Mark Murphy of The Boston Herald. Horford explains how he copes: “My biggest thing, and I learned this at an early stage in my career, was to not read any of that information or see anything, good or bad…One day people love you, the next they hate you, it’s really up and down, and my focus was making sure the team kept getting better as a group, and not worry about anything outside. One thing that helped me was not paying attention to a lot of things.”
• 76ers president of basketball operations Bryan Colangelo is not speeding up the team’s rebuild and instead appears to be patiently and strategically building a contender a la Sam Hinkie‘s “The Process,” writes Bob Cooney of Philly.com.
• The 76ers will hold a pre-draft workout on Wednesday, reports Keith Pompey of Philly.com (link via Twitter). The scheduled participants are Jordan Bell (Oregon), Thomas Bryant (Indiana), Tyler Dorsey (Oregon), Elie Okobo (Élan Béarnais Pau-Orthez), L.J. Peak (Georgetown), and Steve Vasturia (Notre Dame).

Here’s more on the upcoming draft:

• Hamidou Diallo will withdraw from the draft and play at Kentucky next season, Jeff Goodman of ESPN.com tweets. Several NBA teams had interest in Diallo and Adam Zagoria of Zagsblog (Twitter link) reports that the Nets and Jazz were the two teams that had the strongest interest in the athletic wing.
• Josh Jackson is expected to come off the board early on draft night, but Bryan Kalbrosky of Hoops Hype speculates that Jackson’s off-court troubles could cause teams to pass on the Kansas product. Jackson was charged with a misdemeanor back in December for kicking and damaging another student’s car door and taillight. He pleaded not guilty to the charges and ultimately signed a diversion agreement which calls for him to attend anger management classes as part of its conditions.
• The Lakers worked out several prospects, according to Joey Ramirez of NBA.com. Kadeem Allen (Arizona), Jamel Artis (Pittsburg), Sidy Djitte (Clemson), J.J. Frazier (Georgia), Josh Hawkinson (Washington State) and L.J. Peak (Georgetown) all participated in drills for the team.
• Ike Anigbogu, who is expected to be taken in the first round, is dealing with a knee injury, Rod Beard of The Detroit News tweets. The ailment forced the UCLA product to miss a workout with the Pistons.

There’s more draft news on lottery day:

• Colorado’s George King will also return to school next season, Rothstein reports. He averaged 11.1 points and 6.8 rebounds as a junior. Stephen Thompson Jr. is heading back to Oregon State, Rothstein adds. The sophomore guard put up 16.3 points and 3.0 assists this season. Both were outside the DraftExpress top 100.
• Anzejs Pasecniks could be the next young Latvian star in New York, writes Brian Lewis of the New York Post. The Nets reportedly have interest in the 21-year-old, who was considered to be a similar prospect to Kristaps Porzingis when they were growing up. At 7’2″, Pasecniks would fill a need at backup center for Brooklyn, which holds the 22nd and 27th picks in next month’s draft. “I don’t want to say he’s Porzingis, but he’s a reasonable facsimile,” said international draft expert Fran Fraschilla of ESPN. “I don’t want to give the impression he’s unathletic, because he’s not. He gives you length, he gives you shooting, he can protect the rim a little bit.”
• The Bucks will work out six players today, according to a tweet from the team. Scheduled to participate are Kentucky’s Hamidou Diallo, Georgetown’s L.J. Peak, SMU’s Sterling Brown, Wisconsin’s Nigel Hayes, Utah State’s Jalen Moore and Louisville’s Deng Adel.
• North Carolina center Tony Bradley will participate in a workout with the Knicks on Wednesday, tweets Ian Begley of ESPN.com.
• The Lakers have four players coming in for a workout on Thursday, tweets Baxter Holmes of ESPN.com. Participants will be Xavier’s Trevon Bluiett, UCLA’s Isaac Hamilton, Michigan’s Zak Irvin and Miami’s Davon Reed.
• The Ringer has issued a draft guide ranking the top 60 players available. Markelle Fultz is the site’s top pick, followed by Josh Jackson, Lonzo Ball and Malik Monk as a surprise in the No. 4 slot. Seven guards are likely to be taken in the lottery, writes Kevin O’Connor of The Ringer in a separate piece.

According to Adam Zagoria of ZagsBlog.com, the Nets will bring in Rawle Alkins, Melo Trimble, Kobi Simmons, Davon Reed, Amida Brimah, and Omer Yurtseven for a group workout on Tuesday. On Thursday, Brooklyn will take a closer look at Josh Hart and Tyler Dorsey. Meanwhile, Purdue’s Caleb Swanigan is also expected to be a part of that Thursday workout, per Nathan Baird of The Journal & Courier (Twitter link).

As Brooklyn does its homework on the non-lottery prospects in this year’s draft class, let’s check out a few more workout-related updates, including an additional note on Swanigan:

• As Baird notes in his previously-linked tweet, Swanigan also has a workout lined up for May 22 with the Magic. That session will take place just two days before the deadline to withdraw from the draft and retain his eligibility — Swanigan appears likely to take that decision down to the wire.
• One of this year’s top point guard prospects, Dennis Smith Jr., worked out today for the Magic, as Josh Robbins of The Orlando Sentinel details.
• The Bucks brought in six prospects – JaJuan Johnson, Dwayne Bacon, Trevon Bluiett, Tyler Dorsey, Damyean Dotson, and Davon Reed – for a group workout on Monday, according to the team.
• Georgia guard J.J. Frazier has workouts lined up with the Bucks, Kings, and Lakers after getting a look from the Timberwolves today, tweets Adam Zagoria. L.J. Peak and Antonio Blakeney are among the prospects joining Frazier at Minnesota’s group workout today, tweets Darren Wolfson of 5 Eyewitness News.
• Marcus Keene, Tacko Fall, Michael Ojo, and others are participating in a group workout on Monday with the Celtics, sources tell Michael Scotto of Basketball Insiders (Twitter link).

There’s more draft-related news today:

• Sophomore big man Chance Comanche of Arizona has announced via Twitter than he plans to remain in the draft. He averaged 6.3 points and 3.6 rebounds this season and is a long shot to be drafted.
• Cody Taylor of Basketball Insiders examines players who have gone on to NBA success after not receiving invitations to the draft combine. This year’s edition will be held this week in Chicago.
• Kentucky guard Hamidou Diallo may be the best athlete at the combine, an NBA executive tells Rothstein (Twitter link). Diallo is projected to go early in the second round by both Givony and Ford.
• Three Michigan players are headed to the combine, writes James Hawkins of The Detroit News. Moritz Wagner and D.J. Wilson, who entered the draft without hiring agents, both received invitations, along with senior Derrick Walton. Another Wolverines senior, Zak Irvin, also has draft aspirations but wasn’t invited to the combine.
• Wagner will be among six players working out for the Jazz on Sunday, according to a tweet from the team. Joining him will be LSU’s Antonio Blakeney, UCLA’s Aaron Holiday, Florida State’s Xavier Rathan-Mayes, Georgetown’s L.J. Peak and BYU’s Eric Mika.

“This organization has been instrumental in my path and as I look to embark on my professional career, I will carry the many lessons learned,” Bacon said in a statement. “We are truly family here and I’d like to thank Coach Ham, Coach C.Y., Coach Jones, Coach Gates, and the entire faculty and coaching staff for a great two years.”

Assuming Bacon does remain in the draft, as expected, he looks like a possible second-round pick. ESPN and DraftExpress have him ranked 56th and 57th, respectively, on their big boards.

Here are a few more draft-related updates:

• Georgetown’s L.J. Peak will forgo his senior season in college, according to Jeff Goodman of ESPN.com, who reports that the junior forward intends to sign with an agent. DraftExpress ranks Peak as the No. 76 prospect on its big board.
• We heard earlier today that Louisville’s Donovan Mitchell will test the NBA draft waters, but he’s not the only Cardinal who will declare his intent. Sophomore forward Deng Adel and junior forward Jaylen Johnson will also test the draft waters without agents, Louisville coach Rick Pitino tells Adam Zagoria of SNY.tv (Twitter link). Mitchell is the most promising prospect of the three, though Adel ranks 34th on DraftExpress’ list of top sophomores.
• BYU sophomore Eric Mika will enter the 2017 NBA draft, but won’t hire an agent, tweets Jon Rothstein of FanRag Sports. While the 6’10” Mika will have the opportunity to test the draft waters, he could withdraw his name before May’s deadline.
• With the Sweet 16 set to get underway on Thursday, Jonathan Tjarks of The Ringer identifies six under-the-radar NBA prospects to keep an eye on during this week’s NCAA games.
