First - CSU did not meet enrollment goals this year. Tuition pays for education!!   You justify a wildly expensive football stadium and massive losses each year in the football program by saying that sports recruit students. 
There is no evidence that football like CSUs attracts students, just assertions by football fans.  In fact, the demographic that watches college football is not the age or gender that are applying for colleges.  

Football is not merit based like other student athletes such as swimming, that attracts world wide attention from the ages that are applying to college (since it is an Olympic sport) but there are no men's swimming scholarships at CSU and partial ones for women.  In fact, they lose more on football than men's track & field, men's golf, and all of women's sports combined.  More than half undergraduates are women.  So football takes away from other sports.  
And ----   College football attendance has been declining even at the big Div 1 football schools.
