First off, hi all, new poster here. I am a big WKU fan (Jeremy Evans alma mater), and watched him play for 4 years of college ball. Yes, he is very athletic, and yes he is very thin.
Some of you may know, but I will throw this out there anyway. Evans was a high jump champion in the state of Arkansas in high school. I am not sure what his personal best was/is, but I remember it being at (or very near) 7'. Jeremy was also on the track and field team at WKU, and many believe this was a primary reason as to why he never put on much weight (for the record, he did add quite a bit of muscle while at WKU, just not much mass), he has put on close to 10 pounds of muscle mass since starting training for the NBA (a period of 2-3 months). He can put on weight, he will just have to work at it. He is a legit 6'9" (probably 6'10" or 6'9.5" in shoes) and is a very quick leaper. He also has a very large wingspan (I have heard 7'4" but cannot confirm that. He has large hands and catches most everything thrown his way.
About his game. He is raw offensively (mostly scoring on dunks and offensive rebounds), but he can shoot the ball very well for a player his size. He can shoot out to the college 3 point line, but has a slow release. Defensively, he is excellent, but can get muscled out by bulkier post players. Jeremy is very unselfish and will rarely force a play or turn the ball over. He will take a few seasons to get there, but he has the potential to be a very good SF/PF in the NBA. Not a starter per say, but a solid 6th man who brings energy off the bench and can take advantage of mismatches on offense and guard multiple positions on defense. That is about all I can think of at the moment, feel free to ask anything you would like about him and I will do my best to answer.
