I just don't see how the Celtics don't win. They really should have pulled it out with a 3-2 lead last year without KG (and Powe). Now, we just dismantle the best team in the NBA and are riding high, emotionally. The Magic, on the other hand, really haven't had a challenge and have been sitting around for a few days.
It's certainly possible that the Magic could win- of course, but I definitely see them going down in game 1, at least- which immediately gives Boston homecourt advantage.
