Ranking assuming no major upsets outside of those two games. If they lose both those games then Wake Forest leapfrogging us because they beat Clemson is not something we'll even be thinking about.
The point is, BYU has plenty of opportunities this season to prove themselves on the field and they don't necessarily have to worry about getting lucky in order to get a high ranking. They just have to worry about winning. And if they don't win, then they really have nobody to blame but themselves.
