I think there is a decent chance he will run 4 years at St. Marys. I also think he has a small chance at being a drafted.
As a freshman he has helped SMC gain a ranking for most of this season and unless something very odd happens this weekend, will help then gain an at large bid in the the NCAA tournament.
Next year could be even bigger for them with both Mills and Omar Samhan (jr this year) coming back.
Who knows where his game will be in 3 years time. He is barely 5"11, but he is super quick and has great court vision. If he can work on getting some consistency in his shooting, sure up his already decent defending and have 1 or 2 big games in a NCAA tournament, he will be in with a great shot!
