If what's reported—half of the conference wants a change—would the eighth school be the 'fatal straw?'
In a report I've read recently the author pointed out that the B1G and the SEC were the only two conferences who had over 1 billion in revenue last fiscal year. This was an aggregate figure, for football only.
Putting this is a bit of perspective. You know who #1 is: soon to be SEC member, Texas. UGA, coming off their title, came in second followed by ND, soon to be SEC member Oklahoma, Michigan and then Alabama ($127.6m)
10 schools, total, broke the $100 million mark. If we include UT and OU, then add UGA, Bama, AU and UT? Six of ten. (Ohio State, Michigan, and Penn State round out the 10.)
When it comes to the ACC, FSU led the way. They were almost 23 million shy of Tennessee's revenue. (Wisconsin and Iowa had more revenue than FSU.)
The ACC didn't come within $200 million of the SEC.
(LSU, $95m and UF $93m.)
