By the way, let's not feel too bad for the Cavaliers.
They will be the favorite in the Eastern Conference next year, and probably every year as long as they have LeBron. They'll be knocking on the door to the Finals again. LeBron might make it to the Finals six, seven, or eight straight times. There's no clear rival coming down the pike right now.
While the Celts are still trying to figure out how to get the right guys to make it past the first round, the Cavs will be winning 50+ games and dominating the East playoffs. With some luck and the right supporting cast, LeBron will probably win at least one more title. I'd bet on it.
