The number three ranked team with an absolutely top tier defense and is in the conversation for the playoff lost their first game yesterday, so now they aren't "very, very good?" Prior to yesterday they led the nation in turnover margin.
I suspect that before yesterday, they'd be underdogs on a neutral field to possibly three or four teams?
What's your standard for "very, very good?". They'd absolutely be undefeated in the ACC. Unless you count only Alabama and Georgia as "very, very good," you gotta leave the door open for Iowa.
