"We" here are trying to guess what the committee might do. I'd be surprised if a 12-1 UGA is included over a13-0 FSU. No need to speculate, for me anyway, I'll just wait and see what happens in a few days. Hopefully it's not at issue.
I think any P5 undefeated should be in (barring eligibility issues). It could be fun to speculate about Upsets happening around the globe and the mayhem that could ensue.
