Money. Football program had a net profit of $27 million last year.From a monetary standpoint you are more successful with a good FB program. You can still be successful at BB, swimming, etc. My big question is why participate at the top level if your not going to be committed ? I'm about to the point of IU dropping FB altogether. However on your list Duke, KY, Arizona have decent FB programs, Villa and Gonzaga don't have D-1 FB and UConn is an aberration.
People keep talking about IU being "committed" as if that is going to change things. We are never going to compete with OSU, Michigan, Penn St. other than in once-in-a-generation flukes like the Covid year (with a Heisman candidate level talent at QB). NIL is going to ensure that.
