As expected, Pitt not only slid, but fell out of both rankings completely this week. That's no big surprise, since the loss to Notre Dame last week. The Panthers did, though, get a small amount of support in the polls.
Personally, I don't see how you could vote the Panthers in the top 25 after that loss. Pitt now has four losses on the year and lost three in a row. It's pretty clear that they don't belong in the top 25 at this point. And at the risk of skewing towards doom and gloom, the thing is that since they're in a tough conference like the Big East, they may not get back into the rankings this year.
