Yes, they also lost Ilgauskas (largely a role bench player now), a washed up Shaq, and an underperforming Delonte West from 09-10. The core of the team is still the same save Lebron - a bunch of role players. Who on that team is an all-star caliber player? Because you need at least two to win in the NBA.
Look, if you don't like him based on "the decision," so be it. It's your opinion. But he didn't have a talented team around them. He carried them and made a lot of those guys better. Only so much one guy can do.
I dont disagree that he was the leader. But to say he didnt have enough to win while winning the most games in a season and earning the #1 seed isnt realistic. By virtue of being the #1 seed and favorite to win it all would indicate he had enough to get it done.
