I don't recall Trey Johnson ever being able to get inside the paint and score against NBA defenses the way Glock showed last season when he was getting a consistent 20 minutes a game during a stretch when Blake was hurt. Glock's floater and his 3pt shot (both of which are superior to Johnson's) make his game more palatable for the NBA as far as offense goes. The floater is a shot that short players like Glock and Johnson must have to shoot over NBA caliber shotblockers. An accurate 3pt shot is also a necessity to open up spacing for drives since they can't drive using strength the way bigger players like Melo and Lebron can.
