This thread seemed to morph from will LeBron force a trade away from the Lakers to where does he fall in terms of all time Lakers players. I don't think LeBron will play for any other team. I have nothing to quote or otherwise back that up, it is just my opinion. His NBA legacy is not going to be improved by jumping to another team. Whether he wins again in LA or somewhere else, what is the difference. He can attract who is wants to LA. He may not win again but LA is probably still his best shot.
As to his Lakers legacy, I doubt LeBron cares all that much about that. LeBron will be compared to the greatest players of all time, not the greatest Lakers. To compare LeBron to say Kobe in terms of Lakers legacy is like comparing Kevin Garnett to Kevin McHale or something. And even that, LeBron has played for (and won championships on) 3 teams, I don't think any other player has done that. And then you look at someone like Worthy and he was the 3rd best player on title teams. Is he really comparable to LeBron just because he played more seasons with the Lakers?
