Nets Acquire Jarrett Jack In Deal With Cavs, Celts

10:06am: The second-rounder going from the Celtics to the Cavs is for 2015, according to Cleveland’s official announcement on the trade. It’s top-55 protected, and if it doesn’t fall within the final five picks of the second round, Boston’s obligation regarding the pick will be extinguished.

THURSDAY, 9:21am: The trade is official, the Nets announce.

“Jarrett is a proven NBA veteran who will add versatility to our backcourt,” Nets GM Billy King said in the team’s statement. “The team had a need in that area and we are excited that we were able to secure Jarrett to fill that role. Sergey is a player who we have followed closely for several years. He is a versatile forward and will be a welcome addition to our roster.”

WEDNESDAY, 10:02am: The Cavs will receive the draft rights to Ilkan Karaman, Christian Drejer and Edin Bavcic from the Nets, tweets Adrian Wojnarowski of Yahoo! Sports. They were second-round picks in 2012, 2004 and 2006, respectively. The first-rounder going from Cleveland to Boston is top-10 protected in 2016, 2017 and 2018 and becomes unprotected for 2019, Wojnarowski adds (Twitter link).

9:46am: The Cavs, Nets and Celtics will complete a three-team trade that sends Jarrett Jack to the Nets and opens up the cap flexibility necessary for Cleveland to give LeBron James a max contract, as Baxter Holmes of The Boston Globe confirms (Twitter link). Marc Stein of ESPN.com first reported that the clubs were on the verge of a deal. Sergey Karasev will go to the Nets as well, while Marcus Thornton, Tyler Zeller, and a first-round pick are headed to Boston. The first-rounder the Celtics are getting is for 2016, as Jeff Goodman of ESPN.com reported, and Holmes says that pick is coming from the Cavs (Twitter link). The Celtics send a future second-round pick to the Cavs, Holmes tweets.

It appears as though the Celtics will slip Thornton, who’s set to make $8.575MM next season, and Zeller, set for slightly more than $1.5MM, into the nearly $10.3MM trade exception left over from last year’s Paul Pierce trade, as Goodman pointed out. The Cavs No. 1 option is using the max-level cap flexibility the deal creates to chase LeBron, but if not, they’ll reportedly go after second-tier free agents, with Trevor Ariza apparently among their targets.

Cleveland and the Nets were reportedly working for weeks on a trade involving Jack and Thornton, but with the Cavs uninterested in taking back Thornton’s salary, the involvement of a third team became necessary. The Hawks were among the teams the Cavs were reaching out to, but the idea of acquiring Thornton was apparently a turn-off for them. Enter the Celtics, who’ve been looking to acquire assets necessary to enhance their standing for a Kevin Love trade.

The Nets end up with a backup point guard to replace Shaun Livingston, who signed with the Warriors. They also receive Karasev, just a year removed from having been the 19th overall pick in the 2013 draft, to help inject youth into a veteran-laded team. The Nets believe Jack could even start next to Deron Williams, as Livingston did for much of last season, while they were eyeing Karasev during the draft last year, TNT’s David Aldridge tweets.
