I'm really high on Negron as well. Porters mentioned that he told Negron "Next season starts when we land" after the Michigan game. Pointing him out like that to me says they're going to rely on him. I also really like his potential. He's super long and bouncy; a willing defender who seems to have bought into the culture.
I also think Kaifes could surprise. Labeled a sharpshooter but comes in much more well rounded and athletic than Devon Turk or Ben Richardson did. Not sure about his defense but I think he could finish the season with a foul double digit scoring outputs.
Franks physically ready to compete and should be a great rim protector/rebounder. His offensive game is still raw, but after watching him hold his own defensively playoff game game against the top rated center in the country Bol Bol I'm optimistic (

Bujdoso looks like a smooth pass first point. should be able to facilitate the offense in small doses. A lot has been said about his leadership skills which is great moving forward!
