If you're talking best player of the decade, it's KG. If you mean who's accomplished the most in that same amount of time, for sure it's Timmay.
And while I'm up on my high horse, lemme say that Kobe has n-e-v-e-r NEVER had a season where he performed on the level of Wade or Lebron last year, Chris Paul the past two years, or Shaq at the beginning of the decade. On any squad besides the Lakers he'd be Marvin Harrison with Eurosexual leanings. There've been some staggering displays of greatness in the NBA over the past decade, I don't see why the media chooses to elevate this undeserving chump.
