Thanks for pointing this out. There are a lot of myths about Mizzou and Nebraska and their performance, that switching conferences has made a big impact. It has not.
On the flipside people try to claim Nebraska's struggles are tied to being in the Big 10 and make all these reasons tied to recruiting (losing old recruiting grounds, etc.). Bottom line is their recruiting hasn't slipped.
It's REALLY simple for both of these. When Pinkel was coach, Mizzou won in the Big 12 and SEC. When Pelini was coach Nebraska won in the Big 12 and Big 10.
It's all about the coach. If they hire great coaches they will win. If they have bad coaches they won't. It's that simple. People can explain why the conferences SHOULD impact things like recruiting, but the bottom line is that for both schools the recruiting and SOS hasn't really changed all that much. Their coaches have changed, and that's why the results are different.
