There is plenty of evidence to now show that FSU does not have a viable option at backup QB to give them a chance to be competitive against an elite team. They were barely competitive against a below average SEC team and a slightly above average Louisville team.
On the other hand, Ohio State proved they could thrive with a 3rd string quarterback (Cardale Jones) before the playoffs began, because he excelled in their 59-0 dismantling of Wisconsin in the Big Ten championship game.
If FSU wants an example to drive the point home, last year they came from behind and narrowly beat an average Oklahoma team in a bowl game, with Dillon Gabriel quarterbacking Oklahoma. If you look at Oklahoma last year, they were competitive when Dillon Gabriel was healthy, and were not when he was injured (including a 49-0 blowout loss to Texas). Like FSU, they had no viable option at backup quarterback, and the same thing would happen to FSU right now if they had to play against Michigan or Alabama or Texas instead of the two teams they barely beat since Travis went out. They don't have a Jalen Hurts to come off the bench when Tua gets hurt, or a Kyler Murray to come off the bench when Baker Mayfield gets hurt.
