4 years of college to work on his game, learn to play big and to figure out what works and what doesn't. There's honestly very little player development that takes place in the NBA, especially as far as big men are concerned. On the flipside in College from March till the next season is basically nothing but time to work on your game with coaches.
Zo had this thing called an engine. It goes so unnoticed in his game. Dude could just keep going. Loved watching him play. Felt good when he finally got him a ring.
