A better question would be is there ANY back court player in the league today you would consider trading Kobe for?
T-Mac, Wade, Iverson, Allen? IMO NO! None of those guys play much D. The only guy who's so good on O that I might trade Kobe for is LeBron. While I don't believe LeBron is much of a defensive player he is too big to post up.
I don't see enough LeBron to know for sure if I'd trade those two but I do think LeBron has much better court vision and make better decisions at this point in time. I think I would pull the trigger.
