Not saying it would have been "a lot better" to beat OU in the CCG instead of OSU, but it would have been better. A victory over OU would have had the salutary effect of showing the selection committee that the one team that managed to beat us this season is not, in fact, better than us, and it also would have felt great from a revenge standpoint.
And Okie Lite is *already* a 3-loss team. OU's losses certainly aren't worse than OSU losing to fucking South Alabama (!), ISU, and Central Florida. Did you *see* that OSU-UCF game, for chrissakes? At least OU was competitive in their two losses. OSU looked like hammered dogshit when they lost to South Alabama and UCF.
I'd rather get payback by beating the better team. If we're worried about which team matches up better with us, then we shouldn't even be there in the first place.
