if we want a top 25 ranking. Wins are important, in and of themselves, but if they are predominately against weak opponents, a final ranking will be out of reach.
Since independence, BYU has won two games against P5s that finished with a winning season. Bronco was 2-10. Kalani will likely be 0-6, after the Mississippi State game.
After watching BSU and USU, I believe that Miss. State is the only probable loss.
BYU, with a bowl win. could finish 10-4 but would be left out if the final AP rankings.
Since BYU cannot be measured by how it performs in comparison to its conference mates, it can only be judged on how it performs against P5s, particularly good P5s.
