It seemed to me that the Cavs have lately been playing lots of games against opponents on the second day of a back to backs, while at the same time the C's have not seen many tired opponents recently... so I did a little research:
In the 20 games leading up to the All Star break, Cleveland plays 9 games (45%) against teams who are on the 2nd game of a back to back. In the same time span the Celtics played 2 teams, the Clips and the Mavs (10%). Think this might have made the Cav's recent winning streak a little smoother?
Although I will admit to loving a good conspiracy theory, it seems to me that this is statisticly unlikely to be random chance. It does make me wonder about the frequency of playing opponents on the 2nd day of their back to backs across the league, for the full season (but I'm too lazy to do that kind of research). While its been said many times that everyone has to play the same number of games, home and road, as an argument against scheduling bias, it seems to me that this would be a great way to influence a teams record on the down low. Lets face it, any team on the 2nd day is going to be more vulnerable than on the first and this is not a category of scheduling that has to even up over the course of the season.
