Teams that didn't blow it in the semis:
2014-15: Oregon, Ohio State, Alabama (Honestly, we won by 7. It felt great, though.)
2015-16: Alabama, Clemson
2016-17: Alabama, Clemson
2017-18: Alabama, Georgia, Oklahoma (even though they kinda blew it.)
2018-19: Alabama, Clemson
Teams that clearly didn't belong:
2014-15: Florida State
2015-16: Oklahoma. Michigan State
2016-17: Ohio State, Washington
2017-18: Clemson
2018-19: Notre Dame, Oklahoma
Point is, I can think of at least 3 years where Ohio State should have been in and weren't and one where they shouldn't have been in and they were on name recognition, and subsequently got shut out.
The committee got it right once. They might as well include UCF. What's it gonna hurt? It's been mostly blowouts anyway.
