I think the coaches need to redefine his role and game - he's not a sharpshooter from the outside or an instant-offense guy who can carry the bench-scoring. He should be cast as a versatile wing off-the-bench who can put it on the floor and either pass off the bounce or get to the rim and when left open - can hit the open stationary 3. His biggest problem is taking ill-advised perimeter shots either off the dribble or when he's on the move. I think too much pressure was put on him last season as Utah's only real scorer off the bench - and he obviously forced his shot way too much.
To me, picking up his $3.7 million option is a no-brainer. After that, let's see how the draft shakes out and then proceed from there - but CJ can definitely be a contributor to a winning team, and as well as having half-decent trade value around the league.
