I think what we see is what we get. For the Celtics to win against a great team . , they need to have a "ON" night and the opponent needs to over look them.
Celtics can't over power people at will. BEst the Celtics can do with current talent is gang up on the most hopeless bottom feeder teams...and I'm not confident of those games either.
Eventually the Celtics will win some games against contenders , just because the opponent doesn't care or lack of interest or effort. I hate those wins almost more than losses...becasue you know they are hollow.
