The 5 les are a pretty significant argument; Jordan's 6 and Russell's 11 are generally noted as the premier accomplishments of their careers and the fundamental bona fides for their inclusion in any historical Top 5. Tim Duncan's 5th all but ensured that he will retire as a Top 10 all-time player.
I'm not going to try to spell out Kobe's resume, but I will say again that I don't think an argument that Kobe Bryant has had a better career than Lebron James at this juncture is in any way unreasonable. Kobe's got hardware that Lebron can't match; Kobe's got production that Lebron hasn't matched yet; Kobe's got monstrous performances in big games and big moments that are indelibly a part of his NBA legacy -- and, arguably, he has far more of those kinds of performances than Lebron does (and most of the time, he's had to get through a difficult Western Conference without the cushion of getting a couple of walkovers to get him into the latter rounds of the playoffs; and when he was younger, his teams ran that gauntlet with some consistency).
It's all a matter of taste and subjective evaluations, but there's ample room to argue that Kobe Bryant's resume is among the very best ever.
Ranking him, at the end of his career, slightly ahead of Lebron in the middle of his career is pretty reasonable.
