Disagree. Missouri's OOC is much better than WVU's (beat Illinois, to start) and their loss isn't as bad as WVU's (OU vs. USF).
This whole scenario is really interesting though. Missouri's regular season should have them in the National Championship game (and obviously does, thanks to day's #1 BCS ranking). Thing is, if they lose next week to Oklahoma (who is a slight favorite), then Ohio State will most likely get in to the National Championship primarily because they don't have a conference championship game. In essence, Missouri is being punished for this extra game as they have nothing to gain from it.
