But similar, except opposite, to last week, we moved up a spot but lost ranking points. Last week we moved down a spot while gaining ranking points. That's the way it works sometimes.
As to RPI, that's (one of) the problem with RPI. There are absolutely times that just playing a match will make your ranking go up, even if you lose, and conversely times that your RPI will go down by playing a match, no matter the score. There are teams that Pitt could beat 25-0, 25-0, 25-0 that would cause Pitt's RPI to go down. On the other hand, there are teams that Pitt could lose to 25-0, 25-0, 25-0 that would cause Pitt's RPI to go up (although there probably aren't more than a couple of them). And that just doesn't make any sense.
