A top team, other than perhaps Michigan, would beat Akron just as easily as Appy State (when they were FCS), beginning, end, middle.
If they don't, they aren't a top team.
UGA struggled a couple years ago with somebody, they almost lost in fact, at home. I saw that offensive line and realized they would have a tough year and they did. Whether that team was FBS or FCS made no difference other than being 51-10 versus 55-6 or something. Good teams won't struggle with lower third FBS teams any more than FCS teams.
Nichols State it was, horrible showing.
