Bulls fans would embrace LeBron. Comparisons to MJ are inevitable, but no one would realistically expect him to win 6.
Staying in Cleveland is stagnation. They're not going anywhere. They're a team that wins 60+ games during the regular season only to get embarrassed in the playoffs.
I don't see how the Knicks are a better option than the Bulls. At all. They're about to lose David Lee. Now, they have Amare. Big deal. Their roster still sucks overall. And they don't play defense. Mike D'Antoni has never stressed defense.
The only team I'm afraid of is Miami. The thing is, though, if he goes there it's probably still Wade's team. LeBron would have to share the spotlight. Garnett was willing to do that. I'm not convinced LeBron is. If he comes to Chicago, it's automatically his team.
