I agree on the minutes issue. But I also think its an issue he's only played a couple of years and even right now hes only playing 20 minutes a game on a short college season.
If he's the next Olajuwon why would the coach no be playing him more?
His team is stacked. Ellis is their most experienced player so he deserves a lot of burn. Plus, Black transferred from Memphis and can only play this year so I think Bill Self is kind of forced to play him.
If I was self, I'd say "screw Black" and get Embiid in there a lot more. Then one would definitely see his PPG, RPG, BPG, and APG climb.
