18 25 vs .500 or better Teams, and everyone is surprised?
But they beat Golden State at home!
Heh.
That game was a huge accomplishment, obviously, but yeah, this isn't exactly anything new. The Celts are good enough to kill bad teams, but have had significantly less success against playoff caliber opponents.
Grande and Max pointed out the Celts have a poor record this year when they don't amass a very large lead at some point in the game. If they don't step on an opponent early, it doesn't bode well.
