better handles
LeBron James career 6.9 ast per game, good for 28th all time average. Kobe Bryant, 4.8 ast per game. Also see turnovers.
better defender
LeBron has more steals and blocks per game on less personal fouls. Kobe ran away from guarding Pierce or Allen in 2008, so we really have to dial in on "prime defense" Kobe. Yeah. No guarding Derrick Rose for him. No no.
better leader
Last 3 seasons with LeBron James Cavs-69.9% winning percentage
Last 3 seaons without LeBron James- 27.8 winning percentage
Last 3 seasons without LeBron James-Heat 42.6% winning percentage
Last 3 seasons with LeBron James- 73.9 winning percentage
Making for a 69.5 winning percentage over the last 6 years. Making for a better winning % than Kobe's 67.6% win percentage for the seasons with Pau Gasol, and of course his 49.1 win % as his teams best player pre Gasol. LeBron has never missed the playoffs in his prime, as Kobe did in 2005 at age 27. Leadership.
