I´m going to copy something Larry Bird a while ago, it's pretty much how I feel about this kobe vs lebron debate:
"But, if you want to have fun, like I did with Bill Walton, play with LeBron. It would have probably been more fun to play with LeBron, but if you want to win and win and win, it's Kobe. Not that LeBron's not a winner, just that [Kobe's] mindset is to go into every practice, every game, to get better."
Both are great competitors and winners, Lebron is a better teammate but Kobe is the best players.
Come on now Kobe really isn't a winner the titles he won are mostly due to his supporting cast and great coaching he couldn't even get Malone and Payton a ring and San Antionio defeated the almost identical Pistons team a year later.
