Kobe Bryant is a 118, while Vince Carter
was a 152 on the Magic. I smell a trade coming!
The +/- stat does have its uses, and it's especially effective for teams to evaluate their most effective lineups, but for a struggling team, it's pretty much a given that many of their good players will be among the bottom. Tyreke Evans is a -170; he's struggling this year, but 29 other teams would still love to have him!
