As far as his attitude, he is showing signs of improvement. If anyone can control him, it's Woodson. In the exit interviews, JR said he wanted to improve his defense and ball handling skills. Still talk till he proves otherwise but when has JR EVER said anything like that before.
As far as everyone ripping on him for his 0 assist, 0 rebound effort in the playoffs GTFO. JR got 7 rebounds or more several times for us, and I saw him reach 5 assists like 10 times (even had a 9 assist game). I agree he needs to cut down on his shotjacking, but if he comes back for the 2.5m, he's a steal.
