You not only have to win, but you need to win big with style points.

Given that the voters in ACC country haven't yet jumped on the BYU bandwagon, the Virginia game provides BYU with a huge opportunity to impress some people. BYU needs to beat the Cavaliers in impressive fashion, and that will help bump up the Cougars polling numbers in that portion of the country.

One more thing. My guess is that people leave BYU out of their polls more as a result of them not being a P5 conference member with a suspect schedule rather than any anti-LDS bias. As they continue to show it on the field, voters will come around.
