Yeah, in the TCU/Michigan game it looked like there were two fairly evenly matched teams where one team made too many mistakes and gave away the game. If they don't make those mistakes they probably win but the teams themselves were close enough to make it a contest.
TCU/Georgia looked like FBS vs FCS.
And Ohio State couldn't come ready to play for a home game that had been dubbed by the media as the ultimate greatest single game in the history of sports and got their doors blown off.
Really this is just a year where one team has this iron clad grip on #1 and nobody else is close.
If TCU wasn't worthy of a 4 team playoff, the only argument left is that it should have been the top 4 SEC teams and nobody from other conferences. I mean that potentially is a valid argument, it makes just as much sense as saying Michigan is better than TCU or Ohio State is some ultimate perfect team after they got stomped at home in a huge hype game.
The Pac and ACC didn't exactly make a case that they needed representation more than Big 12 and Big Ten either.
It'll be very healthy to get a 12 team playoff where the SEC always gets 2-4 teams to reflect its strength, the Big Ten can get 2-3 teams to reflect its ownership of the selection process, and the other conferences just get to play and sometimes win without all this second guessing.
