Edwards wingspan was 6'6" and measured just over 6' in shoes. Yeah, I know, always a debate about whether the 1.5" for shoes is an actual height, but in having been next to Jones, I doubt he was 5'10" in shoes last year.
I don't know how tall Jones really is now, but its a valid concern as high D1 athletes are tougher to get around and finish over and his combination of size/athleticism is a question at the high D1 level. Smaller guys that succeed are usually really quick and while he is quick with the ball, he's not what I would call an exceptional athlete. I would say he is better than Trey Burke was at similar points in their career, but Burke made a huge jump in athleticism from junior to senior year. Will Jones? Don't know.
I really like Jones as a player and has everything you would want in a PG. If he were a little longer/quicker, we'd have offered him already and he'd likely have a lot more suitors. I won't say he is a fall back guy, but we are clearly in a wait and see approach with him.
