In my opinion...if Doc starts Avery Bradley, yes. If he starts Ray no. If he starts Pietrus I don't know.
I don't think who starts at the two guard spot will be the determining factor.
I am of the opinion that if Rondo, Pierce, and Garnett can keep balling the way they have been lately, and stay in that groove they've found together, that we have a good shot against anyone.
The Heat are definitely dangerous. If you start turning the ball over and let them get out and run and have fun, then you are in for an ugly night. Luckily, the Cs are scrappy, and don't let a loud dunk or two by the opposition take the wind out of their sails.
Rondo can befuddle that team, and I think he has shown the ability to get into Lebron James' head a little bit. It takes a smart basketball team to start to wear away at the cracks and get that team questioning themselves. Fortunately, we have the smartest team in basketball.
