I tend to agree, but it's not just about the money.
They brought it back after TCU got snubbed for the playoffs. An interesting what-if is whether or not ou would've made the playoffs had it not been for the game yesterday. Had that not happened it might have been osu.
While I don't like things that favor ou, Texas could be in the same position one day. Any time the committee has to decide on a tie-breaker of one-loss teams then the most recent impression tends to be the deciding factor.
So even though the B12 CPG tends to set up ridiculous repeat games, the current system for the playoffs almost mandates we have one. Of course that can shoot a team in the foot someday, and this normally wouldn't apply to undefeated teams. However any B12 team on the cusp of the playoffs will always want one more game to prove themselves.
