I've watched from about 2 minutes left in the first quarter on. From what I've seen, the Lakers just simply played better I think in the 2nd which has led to this ten point lead at the half. Kobe has made some ridiculous shots and the Lakers as a team are actually playing very good defense. Dwight Howard hasn't been able to take control yet.
I think an interesting side story that could pop up as this series goes on is Rafer Alston becoming unhappy. Because it seems like to me, granted it has only been one half of game 1 of this series, but it seems like Van Gundy is already showing that he prefers Jameer over Rafer. And I'm going to assume that Alston is not gonna like this at all.
