Missouri will be leaving the Big 12 for the SEC. When you look at the bottom line (money) I'm sure it stands to be a good move, except from a travel standpoint where moving to the Big Ten would've made more sense for both parties.
The problem I have is from a sports point of view, especially football. I think Missouri will be able to compete in basketball. They have a traditionally strong program and will be able to hang with most of the teams in the SEC, Kentucky and Florida are the exceptions. The Tigers will strengthen the SEC as a basketball league. They should be able to bring in their share of high profile recruits and finish in the upper division.
Football is a different story. The Tigers have had some recent success in the Big 12 and have gained a reasonable foothold recruiting the talent rich state of Texas. They've also been successful in keeping the best in-state kids at home. There is Texas and Oklahoma in the Big 12, but I think it's easier to recruit against those schools than it will be against LSU, Alabama, Auburn, Florida, and the list goes on. And that's just off the field. I guess it's time to adopt the SEC style of recruiting. And no I don't want to hear how (insert school here) is clean and does it right.
On the field I don't see the Tigers consistently competing with the top tier SEC teams. They can be a dangerous opponent but I just don't see them beating a loaded Alabama team. Or Florida. Or LSU. It is possible that they could pull off a shocker here and there, but that's it. Other than that, they just went from being one of the Big 12's top four teams to being a Texas Tech like program. Someone that will rise up from time to time but will never be a threat to win it all. I know it will piss off Missouri fans, but I see the football team sinking into mediocrity and could ultimately cost Gary Pinkel his job.
