He's probably got one of the highest verts of all the possible guards testing the draft waters. Above average strength. His quickness and speed are pretty average for a combo guard I would say.
Ball handling/decision making are good but certainly not something that separates him from the rest of the class. Monte excelled at these and in my opinion was the primary reason he was drafted.
His shooting, statistically, is just okay. Shot 40.1% from three, 41.4% from 2 and 66% from the line. The three point percentage is above average, but 41.4% from 2 is a bit concerning (I would attest this to shooting a lot of mid-range shots vs. attacking the basket), and his FT% is average for a guard.
Defensively I thought he was solid this past year. I think he can guard a few different positions with his strength and athleticism, and is something he could hang his hat on for future NBA prospects.
Given what he can do athletically and the times where he completely took over certain portions of games this year, he could get a late second round grade, but as a lot of you have said I would think he's encouraged to improve his shooting, FT% and his quickness in college for another year. If he does those things, sky's the limit.
