They give up almost 250 ypg compared to 220 by UM. But, Oklahoma's D-line was able to disrupt Harrell all night long. I can think of a few good guys on the UM D-line that would salivate over the same opportunity.
I don't see any downside to the matchup. People remember which bowl game was reached, not necessarily the outcome. Going in to the Cotton against Texas Tech, no one would believe UM could win the game. With that thinking, they have nothing to do but impress. I think it's a favorable situation to be in considering the matchup.
