I think the media are purposely choosing the Heat because they know whats at stake for them
Ever since they introduced themselves with that concert and laser show, they have built up unreal hype. It was projected that they would win 72+ games and run away with the title. So when they struggled and looked like the flawed team that they are, ESPN and NBA TV have tried their hardest to make excuses for them
They know so many things are riding on this series
If Lebron can't get past the Celtics it would be the most embarrassing thing in the History of the NBA. A heralded Jordan part II who got millions of dollars in endorsements straight out of high school. If he loses this series, it would be a big red mark on his legacy
So even if the Celtics win, I expect there to be a headline of "Miami Heat Big 3 fall short"
Instead of "Celtics prevail over the Heat"
And thats why I wish they would shuttup all they are doing is jacking him up he's going to come at us like an animal. We better be ready to take some charges. 
Lebron is going to be charging in the lane like a bull, lets see who has the guts to stand in there and take the hit!
I believe that Glen Davis will be there to take some charges from Lebron.
He and the rest of the Celtics will step up big in this series. No playing around this time.
You got it, GF, (TP) ... and Pierce and Rondo have taken charges from him as well. This Celtics team is no bunch of sissies ... they're a very physical team that's not afraid to go to the floor for a loose ball or take a charge when needed.
I'll be surprised if Bosh has much to do with this series, (though he'll probably have one decent game), and I see this as pretty much a cohesive unti against two Superstars and their "entourage' ... I'll go with the team any day.
I posted that the Celtics would win in six, (mainly because of their propensity to have at least one horrible game per series), but I honestly feel like they'll win in five, and I wouldn't be a bit surprised.
Most people are underestmating this team, and have been all year, but there is so much experience, fire power, intensity, and depth on this team, that the world is in for a few surprises ... like last year.
