agreed. The best comp is Georgia. Could Georgia beat a top 5 team on the road if the backup came in with a lead and the defense had to carry the team. The answer is absolutely. That’s why Georgia is #2 and we will be around #9 or #10 on Monday.
Georgia would have continued curb stomping Iowa today if they went to their backup. It's misleading to say "beat a top 5 team" when referring to Iowa. They are not one of the top 5 teams.
If Penn State had to play 1 game to win a National Title, and you got to eliminate 5 teams they wouldn't have to play to do it, you wouldn't even be considering Iowa when crossing those teams off. You probably wouldn't even be considering them if you got to cross 10 teams off.
