From a friend:
"My contacts at Vanderbilt tell me emotions are mixed and their vote is up for grabs. 11 SEC teams have to agree. Texas A&M is opposed. Suggestions are A&M leaked the details in order to build support against the move since it was being done behind close doors without much opposition. Debate within Vanderbilt is if we stay in the SEC we have to commit more than the $300 million commitment recently made or start talking to the ACC. If the answer is to recommit, many are pushing for a billion dollar influx to signal to other SEC teams we aren't going to be your automatic door mat in all sports, except baseball, golf, lacrosse, bowling, and tennis. There is talk of expanding the sports we participate in as well.
Interesting times . . . "
Also mentioned rumor the SEC might balloon into ~30 teams and leave the ACC and Big10 to fight to be the last conference alive (because let's face it - the Pac12 and Big12 are dead).
