Who he's on the court with really doesn't mean they're trying to make him a point guard. He hasn't been playing the role of one.
I don't think they ever tried to force him into being a pg. I think they tried to develop his PG skills, but I don't think they ever tried to force him into playing that role.
body control and touch, sadly, aren't a learned trait. You generally either have it or you don't. That's why I never thought Iguodala had #1 type offensive talent in him, not the lack of a jumpshot.
Sam's just an idiot. I don't think there's necessarily coaching to overcome that.
