Having spent seven years coaching college football, I can tell you that we needed at least 50 players who could play on game day. That includes all specialists as well as the twenty two starters and the special teams guys. Oh yeah they could play both ways and all those teams but they would be injured in about two weeks and that would be the season. You have to have at least that many in the pipeline, I mean you don't just take 50 through four years and start all over. You have to coach them because it takes a heck of a high level of proficiency to play college football I mean it is specialized you know. Last year the division one football tv packages for all cable and broadcast tv put together totalled well over 3 billion dollars. The University of Nebraska paid for an entire science wing with football money. Their professors are being paid with quite a bit of football money. They ain't scared of it partner, they cant do without it. Most of the wrestling programs were sustaining themselves with private donations, friends of the Universities, fund raising, and gate. I promise you they cut them because title IX was going to make them match sports numbers of sports men and women and they didnt want to add womens sports. Football sustains itself. It pays its way, they get the devil beat out of them to play it, its a wash. How many does it take to make a girls basketball team, volleyball team, ah heck this is common sense.
