USF all time winning percentage is .580 vs Marshall's .518, with us playing in a BCS for 5 years.
Yes USF is much better than Marshall.
The AAC ended 2017 with 3 ranked teams including your very own arrogant fan-having USF Bulls at #21.. CUSA had 0.
2018, ended with the AAC having only 1 top 25 with another 1 receiving votes. Throughout the season however there were again about 3 teams in and out of the Top 25 including, again, your arrogant fan-having USF Bulls. Again, CUSA without a sniff all season.
Yes the AAC is much better than CUSA.
It is reasonable for USF fans to be embarrassed in losing by 3TDs, at home, in a bowl game to Marshall. It is not arrogant.
