I think that Boston might be the better matchup. We blew a couple games against them this season and they aren't going to blow us off the floor ever.
Miami has two of the three best players in the league and they seem to be peaking at the right time. Melo always plays well against those guys and is a handful of a matchup for them, but those two can score 40 at anytime and Bosh will get his 18-22pts vs us.
Amare with a little rest is a monster and he will outplay KG and I think the same goes for Melo when it comes to pierce. So that leaves two players we really have to worry about Rondo and Allen. Jefferies can bother Rondo a little and we can alternate douglas/fields/carter on Rondo and Allen.
I think the Celtics might be the better match up
