Lebron said it himself " "Not one, not two, not three...not seven". I conclude the only possible answer is ZERO. He said it himself. He sure isn't going to win 8 so I'll take him at his word and go with zero.
Seriously, this is the best shot he'll ever have and they've had a very nice run but this team is still flawed. Too small inside and very little post up game with Bosh may not be enough. Dallas is more balanced and playing phenomenally right now. I think Dallas wins this series.
