I'm a Mizzou fan, and I would agree that 6-2 is wishful thinking. But if Mizzou's future in the SEC looks anything like their past, a more likely scenario is that Missouri will upset someone (not Alabama), like Georgia or Florida, but then lose unexpectedly to someone like Kentucky of Vandy.
If I were to bet (and I learned never to bet on Mizzou games a long time ago), I feel confident that Missouri should beat Kentucky, Vanderbilt, Tennessee, and Texas A&M (for the record, a lot of folks on this board seem to think, for some reason, that A&M is the stronger program of the two. They're not. A&M has been underperforming for about a decade now. Mizzou's beaten them the last three times we played them, and I don't think they'll be better next year than this one with their coaching transition). So 4-4 is where I'd put us, with a slight chance of pulling off an upset in there to bring us to 5-3, which would be a great start, in my book. But 5-3 is the ceiling.
6-2 is definitely wishful thinking. As is, by the way, the thinking of those who imagine that the magic of the SEC is so powerful that we'll struggle to get past teams like Vanderbilt and Kentucky on a regular basis.
This is going to be a long off-season because Missouri fans can't wait to get started in the SEC. And being a native of Columbia, MO, I'll be sure to post a list of good places to eat in advance of the Alabama game. We're looking forward to hosting you!
