But the dominance by OSU and Oklahoma in their respective conferences is nothing like Alabama in the SEC. There is a lot more teams to challenge Bama then what Oklahoma and OSU have to deal with.
These don't indicate a lot of difference in the "dominance/challenge" regarding conference superiority. Perception is it has been easier for Clem and OU but that may just be that...perception. OU has lost the most conference games in that period. It looks to me like Bama and tOSU are equal in dominating their conferences. AGAIN, both have won four of six conference championships since the inception of the CFP. And both are the only teams to have NOT won their conference and still received a CFP bid.
