... I guess that would explain why the Bulls swept the Heat in the regular season, only to lose to them in the playoffs. Their old legs just gave out from under them...

In all seriousness:
(a) I agree that, while the window is almost shut, there's still a year left, and
(b) Not enough credit has been given to the Heat for turning around their season. They didn't look that great early on, losing lots of games early in the season to teams like Boston and Chicago. But they improved over the course of the season, and were able to kick into high gear in the playoffs.
