Dwayne Wade is a bad example because he DOES make his teammates better. See his 6.3 APG average, his defense and his ability and willingness to rebound from the guard spot.
I didn't mind seeing Rivers take shots. I minded seeing him beat his man off the dribble, get triple teamed and not kick it to an open shooter. I minded him constantly ignoring the post. I minded him looking annoyed when his teammates would miss a shot, as if he never missed one.
You ever play pick up ball with guys like that? It sucks.
He has all the potential in the world and I think he'll figure it out, but he needed a leader, not to BE the leader.
