LOL! You think the Heat's defense is better than Chicago? Uh, doesn't Chicago have the coach that was the masterpiece of Boston's championship defense?....LOL! I'm being sarcastic but seriously, I'm shocked Miami's defense has been THIS good. With the Chi coach I really thought their defense (being the best in the league) would do the job but it hasn't as much as I thought it would.
I Absolutely do. Where have you been all season?

Lebron is a shutdown defender (just ask Rose). He's also great at playing the passing lanes.
Wade is a shutdown defender. He's also great at playing the passing lanes and has UNBELIEVABLE anticipation and timing when it comes to blocking shots.
Chalmers is an excellent defender.
Joel Anthony is an excellent defender and a great shot blocker.
Chris Bosh is actually better than advertised. Solid.
Udonis Haslem is also an excellent, hard-nosed defender.
The Heat are extremely athletic and stifling defensively. It's why Rose, the MVP of the league, has looked LESS than ordinary this whole series. The Bulls are an excellent defensive team, but when the Heat turn it on their defense is just on another level.
Wow! Dwayne Wade with 3 blocks in about a minute of overtime. I tell you, when Wade and LeBron are clicking DEFENSIVELY, the Heat are nearly impossible to beat.
Yea man. For real.
