"Barely squeaking by" Florida is still a really good win, whereas practically no one respects Ohio State right now and hence crushing them wouldn't have that big of an impact, so I'd be very surprised if that happened. If the Fiesta Bowl was looking to get a "split title" angle going, they would be much better served by picking Utah instead of Ohio State, but I doubt they care much about that aspect.
No one respects Ohio State and your solution is UTAH? Okay.
