Hmm...I'd say these are the best players per respective team:
Miami- LeBron
NYK- Carmelo
Indiana- George
Brooklyn- Williams
Chicago- Rose
Atlanta- Horford
Boston- Rondo
Milwaukee- Jennings???
Chicago and Boston are already without their best players. Chicago has handled it better in the regular season, but I think we could beat them in a playoff match-up.
Take away LeBron from Miami, and they are still a good team. Take Carmelo off the Knicks, and they'd stink. Indiana would be ok, but I think the C's can beat them as is, so without George, I think we're better. Brooklyn wouldn't be terrible, but without DWill they'd be about on par with Bos/Chi.
To me, I'd think Miami, Bos, Chi and BKN would all have about equal chances.
But that isn't how sports work. Injuries are as much a part of the game as anything. Seems like a debate in futility.
