Kobe's the best of the 00s because he's the only dude who ain't have peaks or valleys in his career. He's been consistent every year as one of the top 3 players and putting up 27/5/5. Duncan/Shaq were great in the early 00s but tailed off at the end. Bron was around in the beginning and only got to Kobe's level in 08. Kobe's the only dude to be arguably the best in the league every single year of the decade.
That by itself should make it obvious that he's the best.
