If they get the Heat, they're a first round exit. Otherwise they're a 2nd round exit.
Nah, the Heat don't scare me. Dwyane Wade is a great player, but he's not great enough to carry the Heat past a 50 win team. The Heat are a pretty bad rebounding team, too, so it's not like they have a huge advantage in terms of size or athleticism in the front court.
The Bucks worried me, but without Bogut they're not a big deal. Bogut made that team, and the Celtics couldn't defend him. Without Bogut everybody else on their squad is much easier to defend, and they are far easier to score on.
The Bobcats are probably the toughest low seed in the East, but the Celtics match up well with them, too.
