Well to be fair, Amida took a bunch of shots that weren't dunks and didn't shoot anywhere close to 70% on those attempts. Were all of those FGA him playing out of his "role"? If he understood his "role" as you implied it to be, then why attempt anything outside of a dunk?
By simply watching him play, you, me, and everyone else knows that his role included making moves both with is back to and away from the basket.
A big man that is inefficient in his ability to score when he isn't physically placing the ball in the hoop is not a plus. I don't think its beyond his role as a center to make post moves and score the ball from 10 ft and in.
Again, this isn't an attack on Amida-- I love the kid and think he's one of the best centers in the country, as many people do. BUT he isn't a scoring threat if he isn't open for a dunk or catching an alley-loop. I think thats a very fair conclusion to draw from what we have seen the last 2 seasons.
