Honestly, while I was watching the game last night I didn't think "Wow, the Celtics are playing superb!". Instead, I thought that Miami was playing terrible. As a whole Miami does not impress me one bit, and I think this series kind of is over if the Celtics keep up the defensive intensity.
What I liked most about last night's game, outside of the win, was that Pierce, Rondo, and especially Perkins all played great defense. They stayed in front of their man, and they provided great help D (especially Perkins). Compared to how Perk played in the 1st game, this was night and day.
