I've spent these last few years fortunate enough to witness Snaer's greatness here at FSU and feel I can provide some insight for those that haven't had this privilege. As a diehard Florida St. fan I can admit that I am quite biased, but at the same time I feel like it provides valuable perspective.
He is one of the most respected player in the history of our program and is just a straight up winner because he of his inhumane work ethic. He is a gym rat's gym rat.
Snaer's defense is top notch and is one the best perimeter defenders in this draft class. He has the size and defensive skills to defend at a high level straight out of college. It would not surprise me if he routinely shuts down opposing shooting guards throughout his career in the NBA.
His offensive game is not as developed but don't let his senior year stats mislead you-- he's actually quite effective if he can be used correctly. On the ACC championship team he had others that could set him up and he thrived in that sort of offense. He cannot carry a team nor do I believe that he will be that effective of beating guys off the dribble. At the same time, when he can get spot up threes, passes on cuts, backdoors, etc. he is a very efficient player. One piece of evidence can be seen in his 38% three pt pct.
Of course everyone always talks about how "clutch" he is. I'm personally not a believer in clutchness- it doesn't pan out mathematically- but there is something just so special about five buzzer beaters against five ACC teams. Everyone likes his Duke buzzer beater at Cameron Indoor- one of the greatest moments of my life- but my favorite was against Ga Tech at McCamish Pavilion.
Like I said earlier, the respect he has gained at FSU is unmatched and is just what the Magic need at a growing period like this.
In fact, if you would like a very high quality read, I recommend this piece by Michael Rogner. This article does a great job at demonstrating what kind of player Michael truly is and why drafting him would be a very wise decision.
