Just got to thinking:
If the college football playoffs give about $1 million, and most guarantee games for D-1A competition is $1 million. The average SBC football budget was around $5,000,000 before the year. That leaves a sizable, but manageable difference of $3 million to come from ticket sales, sponsorships and student fees.
The Nienas report figured $1.25 million from student fees in 2004, when enrollment was 24,000. It is now over 33,000, so using rough math, the revenue should be $1,750,000.
So quick math
Student fee $1,750,000
Playoff payout $1,000,000
Guarantee game $ 1,000,000
That leaves $1,250,000 from other sources, if UTA is to hit the average SBC budget. Now also keep in mind that playoff payout will come through the conference, but it doesn't include other conference revenue from football, like bowl payouts or TV contracts.
