I understand where your coming from. I'm a Umass Alum and I am a big fan of Forbes as well. I'd love to see him get playing time in the NBA.
There a million players like Gary Forbes in the NBA. Your right, he slashes, he plays hard, takes it strong, and he gets on some hot shooting streaks too.
Sounds a lot like Paul Pierce doesn't it, or maybe Kobe, or Lebron.
The point I'm making is, usually the guys that play the position and role that Forbes plays are Super Stars. I'd love to be wrong, but Forbes will never be a Super Star in the NBA.
To be effective he would have to settle in as a role player. Make a consistent jump shot. Throw down the occasional dunk and ignite the crowd. 10 - 15 mins a game.
