Winning game 2 would be nice for me, because it means that Boston (even if it's just for 48 hours):
a) Finds themselves tied with Cleveland in a playoff series
b) Steals home court advantage
c) Shows Lebron and the world that they aren't going to just lay down and die
If they did that, then even if they got swept in the final 3 games, I'd be proud.
I'd be content with either of the following:
1) Force a game 6 by winning two (any two) games
2) Force Cleveland to win at least one game in overtime
3) Force Cleveland to win at least two close games that come down to the final few possessions
Basically anything that shows off this team's competitive spirit and convinces the world (and upcoming free agents) that the Celtics are one or two pieces away from being a serious threat in the East.
