No. 5: BYU vs. Utah State, Oct. 5, 2012
Some might scoff at this, but the 6-3 slim victory proved to be an impressive one. The Aggies won the WAC, finished with a 11-2 record, and were ranked No.16 in the final AP poll.
Believe it or not, this is the only win of the independent era where the Cougars beat someone that finished ranked.
