No. He is still a great player, but his best days are probably behind him. So if most people are not convinced yet that he is the best ever, then I doubt that anything he will do for the rest of his career will change their mind. His statistics are also not quite as impressive as a Michael Jordan or a Wilt Chamberlain.
Kobe has probably been criticized as much or more than any great athlete that I have ever seen. Many people criticize him for not being the best ever, which is a ridiculous criteria to judge someone by. He plays his butt off, has an amazing work ethic, is always willing to take the big shot, plays through injuries, and has piled up some impressive achievements. He does, however, shoot too much sometimes, and he tends to whine when he loses. All in all, however, I would take 12 guys like him on my team any day of the week.
