Agreed -- I figure the biggest driver behind Adams being way above others certain stats is his usage and what this team asks of him is way above what was asked of the other guys sophomore year.
That being said, he has shown clear evidence that he improved his shot, very good distributor, and generally seems very poise & consistent. Plus how about those rebounding numbers? Ollie has talked about guard rebounding and here's a good exhibit showing the work put in there.
