First, let's not forget about Jerian Grant - he's been productive for the most part. He makes things happen on offense.
Regarding Jimmer - the one report says that he doesn't want to change his game - that he's tough to coach/mold. Well, as far as he's concerned, he could be everything that Steph Curry is today. Shoots from anywhere, not fast, but deceptive and herky jerky. It's the freedom and confidence to play in his own unique way which makes Curry so awesome and unpredictable.
What we've seen out of Derrick Williams throughout the pre-season and early thus far is what we're looking for from Jimmer. Give him a little freedom to take the shots he feels good taking.
