The Cavs are certainly not a cohesive unit like the Dubs, but you're an idiot for saying LB is not a team player. He's always envisioned himself as a more athletic version of Magic Johnson. He's not Magic, and this personal belief has actually gotten him in trouble at times (see game 4 debacle).He's kind of a dick head. "Follow my lead," let me take you there, I'm the best. He isn't a team player particularly. GSW are the quintessential team. We'll see tonight.
As far as "whining" goes, that makes him hated by fans but doesn't make him a bad teammate. Ironically Kobe is now loved by many fans for his cojones, but most accounts are he was a fairly lousy teammate overall.
If you're picking the best player since Jordan to start a team, you're taking LeBron or possibly Tim Duncan.
