When I think about that sort of thing I consider how often "Iowa's Greatest Games" or "Purdue's Greatest Games" are beating Ohio State. My Facebook thread was full of folks who never post football stuff taking shots at the Buckeyes.
I have long maintained that one of the reasons for an expanded playoff is folks like to see Goliath fall. The ratings for the Fiesta Bowl were high because it is a game Ohio State might lose. Where gains are made is with viewers who don't usually tune in. The gains on this stuff are in the margins. Ohio State is one of the most hated teams. Folks like to see the Buckeyes lose. That's made for gains in the margins.
It isn't an accident that we were ranked number two. (The CFP system is just as gamed as the BCS.) The powers that be get their shot at one of those games Ohio State can lose while also getting a shot at their ACC-SEC final providing a championship winning replay for either of their networks. (And OSU fans tune in to hopefully see the Ohio boy beat the team that took the Buckeyes out.)
It seems a possibilty there are ratings numbers that can be found to back all of this up. Clemson beating LSU probably doesn't play as well in replays as Clemson beating OSU.
I also note that I hadn't watched any of the Sooners this season. I thought they had a shot because I didn't know anything about them. Given how inept they looked and how the next reasonable choices from the Pac-12 likely compared even had we won it is difficult not to see the committee as having chosen LSU for the final. This is all business and business hates risk. Way less risk to the business making Ohio State number two.
