If I had a gripe about exum it would be his steal rate. He gets like none.
Favors' passing is looking good too.
With Favors/Gobert we could have a defensive WALL with good court vision... they both just need to keep expanding their offensive repertoires for the pairing to really work. But I think they'll get there.
Not sure how Kanter fits into the equation. A lot of it will probably depend on how much he's offered this summer. If it's around 10M, then I think the best scenario might be to trade him for assets or a good vet (not sure who) before its time to extend Rudy. Or maybe we'll get lucky and somehow manage to keep all three bigs going forward.
One thing that I am curious to see is how he eventually becomes more aggressive. You have guys that are naturally aggressive or at least not afraid to take semi rushed shots, see Kobe and Michael Carter Williams 2/20. Exum doesn't try to push the envelope at all, since he is by nature a perfectionist. He doesn't want to be that guy to screw things up. I hope he starts taking more risks around the basket and driving the ball. With his ability to see the court, he could be special if he could use his speed to create.
This is the point many of us keep making. Shooting, handling, cutting, passing, etc can all improve substantially if a player works hard enough. But can you fix heart? I don't think I've ever seen a player who plays as cowardly as Exum. Can that be fixed? It's an honest question. What's the history of timid players who learn to be aggressive? If anything, the opposite is usually true for rookies. They're TOO aggressive, and they force things too often. Experience usually calms you down.
