What I really liked about this game is that all the guys who played in game 7 were big factors. Think about it, JO, Delonte were not there today, Shaq didn't do too much (although his size was useful) and the Celtics still won convincingly.
It's just good to know that the guys who remember how poorly they played in game 7 remained locked in and focused on today's game.
That being said, it was a must-win game just to avoid all the hype coming from the media etc.
