Beating those weak teams by 50+ doesn't really help your final point count in the eyes of the computers, any more than beating them by 30 or so.
After all, ETSU is FCS, so that kind of a beatdown is expected against any reasonably good FBS team.
ULM is a mediocre Sunbelt team, and almost always gets blown out (3 TD or more) by any stronger team in the better conferences.
I don't think that those beatdowns will be a black mark when it comes to the human evaluations of the teams, since each of those better teams have the opportunity to prove themselves against real competition on their schedules.
Besides, when you have that kind of a gap when it comes to talent and coaching, it starts looking more like that hapless 1989 SMU team when we played them. Lou ordered the 4th stringer and walk-on guys to stop trying to score on offense, and on defense, to play very loosely in 4Q, and we still scored some.
