Buy a championship?
If that 2000 team won a Superbowl instead of flopping at 8-8; would anyone have complained?
Miami did what it had to do in 2010 and it gave them 4 straight appearances in the finals with 2 championship. After all, it's all about winning championships, no matter what you have to do.
As for Lebron, he needs to win at least 2 more championships before I would put in in the same level as Shaq, Jordan, Kobe, Russell,Magic. If he can win one more, he moves into Byrd level but he needs 2 more championships.
