Cedric Jackson made the NBA, and as a freshman and Soph at SJU he wasn't good enough to play in the BE. He was probably the worst starting shooting guard on scholarship to ever to wear the uniform.
Greene improved greatly last year. In fairness to him, he was asked to run the offense for almost 3 years, and that wasn't his game. If you can shoot the ball, they'll give you a look. I would love to see him improve enough to make the league. I certainly don't expect it, but whether he gets drafted won't determine whether or not he gets picked up.
Everyone on this board talks about thanking the seniors, but this kid was the only 4 year guy from for 11-12 class who played for 4 years, never complained, never got suspended for anything, and improved every season. If anyone deserves a thank you, it's this kid.
