"Conventional wisdom" would be that the C's have already accomplished what they need to in order to win this series. I respectfully disagree. I think that Orlando is resilient and, not unlike the C's, has a variety of weapons, both offensive and defensive.
Before the Cleveland series, I opined that Boston would have to win more than one on the road and I think the same holds true in this current series. In fact, I think the C's relaxed a tiny bit after Game 2 in Cleveland and got torched.
When the Celtics are healthy, aggressive and focused, I think they are actually the best team in the NBA. Anything less and they are clearly mortal as losses to the less-than-elite 76ers, Wizards and (?) NETS have proven.
Losing tonight's game will certainly not be fatal but I think it will bring us back to Orlando tied at 2. Winning, on the other hand, would make even a cockeyed pessimist like myself think about basketball in June.
