Then why did you bring recruiting classes into it? You keep talking in circles because you know your reasons and talking points are bogus.
The rules don't stipulate that a Playoff participant must be from the Power 5. The rules don't say that you must have a SOS above a certain threshold. Is Ohio St a better team than UC, that's very likely. Will we find out? No because Ohio St lost twice.
If you guys want to take the best team regardless of their record, then why play the regular season. Let's just hold a Playoff every year and we'll have Alabama, Clemson, Oklahoma and Ohio St regardless of record and how they play throughout the year. Sounds great, not.
Whether you like it or not, the most deserving teams got in. Most years that's the case because the best, most talented teams don't always win all their games. I'd argue if you lose multiple games should you really be considered the best, but that's another discussion for another time.
