Still beyond me how he hasn't made his way onto an NBA Roster.
I think that's the green Kool-Aid talking.
Taking nothing away from Cooper, who was a spectacular college player, you have to be insanely good to make the NBA at any size, let alone under six feet. A good reference point is Kay Felder, a similar player who was the 54th overall pick last year and managed to make a roster. Felder's career college stats are almost uniformly significantly better than Cooper's. Yes, that includes assists (7.8 to 6.5).
Cooper is making a great living playing and deserves it, but between his size and his current 33% pro average for three-point shooting, it's hard to see him ever playing in the NBA.
