LarBrd33 the difference is Boston played a terrible team while Dallas played the defending champions..
I can't tell if you're being sarcastic. Dallas just played the Spurs bench a night after the Spurs played an overtime game...
And Dallas looked worse than they normally do in spite of this. They average 110 points on 48% shooting... tonight they put up 99 points on 43% shooting despite the arrival of Rondo and the fact they were playing against the Spurs D-Team.
Again... so far Boston looks better and the Mavs look worse. That could change, of course.
