Great news for the Spurs. It's not Forbes' fault that he was hurting the team as much as he was but the only solution was for him to not be on the team anymore. He's useful in a smaller role but Pop and co. obviously can't be trusted to not overplay Forbes. Forbes is such a good teammate and such a good human being that the coaches can't stop themselves from playing him. Again, not Forbes' fault
The Bucks are the perfect team for him. They have long, athletic defenders. He should be able to survive on that end of the court. On offense, he'll get plenty of clean looks. If Bud can hide Forbes defensively decently enough, I expect that he could have a pretty big season. If Forbes is just asked to knock down open shots and funnel players into his teammates' long limbs, he's going to thrive.
Win, win.
Free at last, Free at last, thank Bud almighty we are free at last.
