Wow. If Pierce hits the fallaway like he ALWAYS does, especially with a good look, this is a moot point. Billups most likely still gets the foul and the game goes into OT and then who knows what happens.
Chauncey and Ray Allen totally took control of the end of that game and it was awesome to watch. Whether or not the C's can "Beat good teams" will be seen throughout the season i'm sure, but as a big Celtics fan I love seeing them play like this with a perrennial great team like the Pistons.
