It's not football school bias. It's chronology bias. Virginia got their big win earlier, so was ahead of us already. Purdue's wins were considered better when they got them (Gonzaga and Duke by double digits) despite happening at the same time, mostly because our Bama win didn't become premium until they just won @Houston this week.
Most voters don't reassess order, they just drop the losers into a spot and move everyone else up that one spot. The only exception is a big win, ala Alabama this week. Then you can move up. @Florida didn't register for most (it did for some) because they're borderline top 50 not top 10.
