they beat their chest because they beat BYU in FB even though they lost to colorado.
to be fair, BYU doesn't have any loss on their BB resume as bad as losing to colorado in football. they did lose to USU...but the utes lost to montana state and unc ashville.
funny, the NCAA database doesn't even count the utes "win" against the "school" in san diego with only 500 students.
