NEW YORK (AP) -- The Southeastern Conference isn't No. 1 in one category: revenues. Forbes released a list Wednesday of the estimated annual revenues for the top conferences in college sports. The SEC, boasting the reigning national champions in football and men's basketball, is fourth. But that will likely change soon, because most of the money comes from television deals, and the SEC is renegotiating its contracts after expansion. The Big Ten is No. 1 with revenues of $310 million -- $250 million of that coming from TV. The Pacific-12 is second at $303 million and the Atlantic Coast Conference third at $293 million. The SEC had revenues of $270 million. Forbes' financial data came from the NCAA, BCS, conferences, news reports and estimates.
