OK. A CCG game that kept a previously undefeated playoff bound team out of the playoffs proves your point that a CCG doesn't hurt. Gotcha.
Yes, Michigan State got in the playoffs. The Big 10 could've had 2 teams in without a title game possibly but Iowa got left out because of it. It hurt Iowa.
And not having a title game didn't hurt the Big XII if we're talking conferences.
Yes, it absolutely proves my point. This issue is about conferences, not individual teams. The whole point is to get a team from the conference into the playoffs. That's the main goal. More times that not, a CCG helps more than it hurts.
The Big Ten would not have gotten two teams into the playoffs. You had Alabama, Clemson, and Oklahoma already in. There was only one spot left. Michigan St wasn't going to jump any of those teams (assuming no CCG against Iowa). The committee has clearly stated that conference champs will get the nod when it comes down to similar teams. You're forgetting that the Big Ten already had that situation anyway, because Ohio St was 11-1. They ended up even behind Stanford, who was 11-2.
The Big 12 didn't get hurt last year because Stanford had 2 losses. The issue is when an 11-1 Big 12 team comes up against another 12-1 P5 team.
