Morrilo is not a B10 4 man. There is no darn way right at 6'7" 215lbs he is going to play effectively defend the B10 power 4s like Morez, Pherrell Payne. MSUs, Purdues, or most other teams. Morrilo wasnt brought here to back up Mirk and guys Mirk can cover. Its ridiculous to think he can match up with the guys the B10, Bama, Tennessee and UConn play at that spot. Its totally a pipe dream. Morrilo can play the 1-3 but if he is asked to defend the 4s in this league he will be abused.
I think the thought of Morillo playing the 4 is as a backup for a few minutes each game. He isn't going to encounter these huge, giant mismatches and the staff isn't going to put him in that position.
