Air Force went 4-8 that year. This is not totally directed at you, but I tire of hearing the excuse of how hard it is to play an option QB and then see teams not as talented as us not struggle in the least.
Not sure what you are referring to but let's look at some notable P5 opponents since 2006:
2006- Air Force lost to Utah (8-5) 17-14
2007- Air Force beat Utah (9-4) 20-12
2007- Air Force beat TCU (8-5) 20-17
2007- Air Force beat Notre Dame 41-24
2008- Air Force lost to Utah (13-0) 30-23
2009- Air Force lost to Minnesota 20-13
2009- Air Force lost to TCU (12-1) 20-17
2009- Air Force lost to Utah (10-3) 23-16
2010- Air Force lost to Oklahoma (12-2) 27-24!
2010- Air Force lost to Utah (10-3) 28-23
2010- Air Force beat Ga Tech 14-7
2012- Air Force lost to Michigan (8-5) 31-25
2015- Air Force lost to Michigan State (12-2) 35-21
2017- Air Force lost to Michigan 29-13
2019- Air Force beat Colorado (Mel Tucker's team) 30-23
2019- Air Force beat Washington State (Leach's team) 31-21
2021- Air Force beat Louisville 31-28
Ironically, they don't seem to be playing as many P5 games in the regular season. But the point is....we are not the only high level P5 team that has struggled against the option in the last 15 years.
Even more evidence:
2006- Army lost to A&M 28-24; Army was 3-9 that year and A&M was 9-4
2006- Army beat Baylor 27-20
2008- Army lost to A&M 21-17; Army was 3-9 that year

2020- Army lost to WV 24-21
2021- Army lost to Wisconsin 20-14
2021- Army lost to WF 70-56
So, there is a LONG list of teams that have struggled against the option.
