The only way Miami can be seen as any kind of threat is if Wade can prove he can be healthy...Which, at this point, is a long shot.
Fact is, they lost LeBron and Allen, replacing them with Deng and Granger respectively. Bosh is still a '4' stuck playing the '5' and McRoberts is an OK offensive piece. If Miami finishes 4th in the East this year, that should be considered a win.
