The Missouri Tigers want into the SEC -- well, they'd deign to accept such an invitation -- and according to Jon Solomon, most SEC schools want Mizzou as well. But the Tigers need nine votes to make it in, and according to the report, they don't quite have it yet.
Here's Solomon in the Birmingham News:
One source said there's a group of presidents that wants to sit tight, believing the SEC can do better than Missouri and that No. 14 should come from the East. According to both sources, Alabama wants to look East and not risk losing its annual game against Tennessee, while Auburn favors adding Missouri and moving to the Eastern Division.
That divisional alignment thing is going to be a pickle. Both Auburn and Alabama have rivalries to protect (vs. Georgia and Tennessee, respectively), but most other currently installed cross-divisional pairings could stand to be played every couple years or so. Unless the SEC can get both of those schools into the East, this is going to continue to be an issue.
