There are three teams that have "competed" (well, two have competed, one has been involved so to speak) in three or more of the CFP "playoffs" - Alabama, Clemson, and ..... drum roll ..... Oklahoma. So far, Alabama is 6-2 and Clemson is 4-2 in the CFP playoffs. Oklahoma is ....... 0-3. They have never won. Oregon and Georgia have only been in one CFP playoff and they both can boast one more win than can Oklahoma. Ohio State fans and ESPN hacks alike will both tell you that one of the reasons (other than Iowa and Purdue) that Ohio State hasn't been back to the playoffs since 2016 is because of the 31-0 loss to Clemson. Well, Oklahoma is 0-3 so when does that record become their albatross? I say now. Enough is enough. Three strikes and the Sooners are out for at least the next two seasons or longer. I don't care if they go undefeated.
Georgia Tech lays claim to a more recent national championship than does Georgia. Georgia can lay claim to not only the most chokes since the advent of the personal computer but they, not Tennessee, are the Michigan of the SEC. Georgia never deserved a third chance in two seasons to choke away a win over Alabama. And Notre Dame? Yeah, that one's obvious.
There is one team other than Alabama and Clemson that has won more than one game in the CFP playoffs - Ohio State. There are only three conferences that have won more than one game in the CFP playoffs - SEC, ACC, and Big Ten. Thank you Alabama, Clemson, and Ohio State. At some point, that has to count for something.
