Let's compare P5 road game records.
BYU 1-3 ok respectable considering the qb situation
USC 3-2 good enough to win their division
Utah 2-2 (one of their best years ever)
UCLA 3-2 one win away from a division title
ASU 1-3 beat UCLA
Arizona 1-5 beat Colorado
Colorado 1-4 beat Oregon State
This is a fair comparison. It would be even more fair if you would consider that every one of these schools gets money, easier recruiting, and access to the biggest bowls just for getting out of bed in the morning.
