Central Notes: Butler, Jack, Cook, Bullock

The relationship between stars Jimmy Butler and Derrick Rose has reportedly been a bit rocky at times, and the discord between the two is a result of Butler not being satisfied with Rose’s work ethic, an unnamed former member of the Bulls tells Joe Cowley of The Chicago Sun-Times. “Personally, the two are great. Professionally is where they have a difference of opinion,” said the source. While Butler does consider Rose a friend, Butler doesn’t have a lot of respect for Rose’s practice habits, and he feels that if Rose is supposed to be the face of the franchise, he should also be one of the hardest workers on the team, Cowley hears. The source also noted that Butler took offense to a comment Rose made during the playoffs last season, when the point guard was asked if Butler had reached superstar status. “I think it’s going to take a little minute for Jimmy to get there,’’ Rose said, according to Cowley.

There are no such concerns regarding Butler’s work ethic from his other teammates and coaching staff, writes Cowley, with new head coach Fred Hoiberg raving about the swingman, saying, “I’m telling you, the amount of work he puts in … even during two-a-days, he would still come in a third time. I mean the guys is unbelievable how much energy he has. He’s just so dedicated to putting the right things in his body, his training, and he wants to continue to add to his game every year. I take my hat off to him. It’s been fun to see everything he’s been able to do out there on the floor.’’

Here’s more from the Central Division:

• The Pacers‘ signing of power forward Kadeem Jack to a minimum salary, non-guaranteed deal was a developmental move, Candace Buckner of The Indianapolis Star tweets. Indiana intends for Jack to play for its new D-League affiliate, the Fort Wayne Mad Ants, this season, Buckner notes.
• With six players vying for the Cavaliers‘ final regular season roster spot, point guard Quinn Cook is making a strong impression on the coaching staff, Chris Haynes of The Northeast Ohio Media Group writes. “I’ve been fighting my whole life,” Cook said. “Fighting to get in a position to be in high school. Fighting to get playing time at Duke and fighting now for a roster spot. I’m used to fighting, and I’m just happy to be at this point, happy that the Cavaliers are giving me this opportunity.”
• In Detroit, Reggie Bullock has made a strong case to secure himself a roster spot on the Pistons with his hard-nosed defensive play, Keith Langlois of NBA.com writes. “He’s done everything he can possibly do for us to think about him because he really goes out and defends,” coach/executive Stan Van Gundy said. “He plays with high energy. I think he stepped up last night and did a good job.”
