Yea, thats the ticket. Lets blame it all on one of the most successful coaches not just in wins, but in preparing and developing kids for the NBA. Roscoe wanted to play the 3, but one of the best talent evaluators and player developers saw him as a 4. Along with the fact that Jeremy Lamb was essentailly playing the 3 in a three guard offense.
AO thought he should be playing over Drummond who went onto being a lottery pick and a top NBA rookie. Drummond at 7' and a freakish athlete and AO at 6'9" with hands of stone just didn't work well on the court together and Calhoun deferred to Drummond as being the better all around weapon. Tell me what was wrong with those decisions.
As for Deandre....freshmen have always taken time to catch onto what Calhoun was doing with and for them. Calhoun pushes and demands and for some it takes longer for the lightbulb to turn on and see that defense and rebounding will get you on the court faster than a stylish dunk or dribble. Deandre's "development" (i.e. playing time) as a freshman was also hampered by Lamb who played more than 30 minutes a game and having to find PT for Giffey, Roscoe, AO and Drummond as the primary big men. Deandre blossomed as a sophomore and is a borderline lottery pick if he can contine to improve next year. This isn't all Ollie's doing, it also has a lot to do with what he learned under Calhoun.
