The "Mizzou won't compete" talking point just reeks of tardishness.
Why? What have they done in the last 10 years to make you think they could be better than an average team in the SEC?
I'm just saying they won't be significantly worse. They will either be in a division with both UK and Vandy or Ole Miss and Mississippi State. They are better than those programs already. Tennessee and Georgia are down. South Carolina and Arkansas are nothing special. They already compare favorably to aTm.
Yeah, they have a couple more OU/UT caliber programs to face, but if the money is there, the competition shouldn't scare them away.
I think the things that people are criticizing are assumptions made by Mizzou fans in terms of how they'll maintain or increase success in the SEC. Instead of saying things like, "Well, we're on par with Kentucky, Vandy, Miss St., etc.," they're saying things like, "We''l start recruiting Georgia more. We'll have more success in Texas. We'll be on TV more."
All of those things are, mostly, wild assumptions that you can't prove at all, but people are accepting them as gospel.
Ultimately, and this is the same for all fan bases, Mizzou fans are overvaluing their place in the world and how easy it will be for them to have success. I think the fact that Arkansas and South Carolina have never won a conference title tells you what you need to know about how difficult it will be to break into the hierarchy of successful SEC programs.
