Yea, the C's shot themselves in the foot in that game. Billups also got away with a (blatent) tackle and take away, when he knocked Rondo down and stole the ball from him. The announcers were almost in shock that it didn't get called.
Anways, it's the NBA, the regular is extremely long, and the most important thing will be keeping their top players healthy for the playoffs, because we all know they've got a very good team, that could be a contender right now.
Oh, and Rondo had a great game offensively, and I'm very happy with the developments he's made over last year. The funny thing is that I couldn't understand why they brought in Sebastian Telfair last year, as I thought Rondo would end up being the better player. Big Baby seems to be developing too, which is also nice.
