That's because the media are a bunch of potzers. Missouri was ranked this year based on what they lost from last year's team. People figured, wrongly, that because Mizzou lost Daniel and Maclin and Coffman and their coordinators that there was no possible way they could be as good. And they probably won't be. But they could be the North winners with the team they have, especially if everyone walks in the door thinking the Tiggers are just going to roll over.
Missouri is a beatable team. Several teams proved that last year. Missouri is untouchable if we play like we did last year, though. We have to bring our best to the game, and if we do, we have a shot.
That sums it up pretty well. The North is a three dog race. I would give the edge to Kansas at this point (I think they have the most polished offense and certainly the best QB - all three at this point have defensive questions to answer) but the margins are slim. If I had to guess the schedule differences may end up tipping the scale favorably to whomever wins. And also whomever avoids losing to someone they should beat.
