Let me put it this way. Hypothetically, say UCF beats Navy next week and they jump us in the ratings. They'd then stay on top of us until we played, most likely. That's 5 weeks of them being the G5 media darlings that we lost out on. We don't magically just gain all that "best of the G5" perception back after beating them. It's akin to USC having to vacate a national championship. It didn't magically remove their perception of greatness as a program those year(s).
I'd rather they lose to Navy and stay far in our rear view perception wise. We don't need any "help" getting the NY6 game now that SDSU has lost and CFP isn't happening. There's nothing good to come out of an undefeated Black Friday matchup for USF, only the American conference. Besides, no-loss USF vs. 1-loss UCF is still a compelling matchup, it's not like the American is losing much there either.
