So, let me ask you this question. Basketball is one of the few sports where, if one is comparing contemporaries, an answer can be reached by each player engaging in a game of one-on-one.
You think LeBron can beat Kobe in a, say, best two out of three.
If you're talking about Lebron TODAY vs Kobe TODAY it's a blowout. Kobe is not the player he used to be. He's on the decline of his career. Anyone who who watched this season would probably agree.
If you're talking about Lebron TODAY vs Kobe 7yrs ago, it's a much closer contest.
Lebron has been the best overall player on the planet for a few years now. Better rebounder than Kobe, better passer than Kobe, as good defensively, and as good a scorer.
