i still think one of the biggest differences is Kobe vs Tim. Tim is a real leader who was willing to give up looks and allow other guys to flourish without any grudges. as a result, everyone else falls in line cuz there's no way they can complain when Tim sets the lead.
over in LA, Kobe is still somehow just as arrogant in refusing to concede to teammates. his version of leadership is to throw guys under the bus in the media, and even though he's more efficient this year scoring-wise, he blames everyone else for his shortcomings. trade Kobe for Lebron straight up and that Lakers squad would've been steam-rolling all competition.
