To set the record straight, Cousins wasn't really forced to play the one. That's where he wanted to be. He was a combo guard who played the point his senior year in high school to prepare him for the next level. It just didn't work out as well as he had hoped.
I agree about his shot release. What an improvement from what we saw last year! Truth is, Isaiah has improved in every phase of the game, from his positioning on defense to his mid and long range shot, to the confidence he's showing.
The move away from running the offense no doubt helped. But when a player makes the kind of strides we're seeing now, you can bet that he did the work in the off season to get there.
