I like May's overall optimism and point, although his evidence/argument is a little lacking. Point 1 is fair, Point 2 refers to Quis and Sasha as reasons we'll beat the Heat (Quis can't keep up with Wade and would be obliterated by Lebron, Sasha actually might be able to do something but he's not going to get PT). Point 3 is probably fair but, as others have pointed out, just puts the ball in Lebron and Wade's hands more. Point 4 is just a hypothetical that, if true, would support his claim, but all he really says is that "it's not outside the realm of possibility." That's not exactly compelling. And point 5 is just silly.
The Celtics have a great shot at pulling an upset in this series, but May is really stretching with some of these points.
