The Utah boosters put a ton more money than they could sustain on an annual basis this year to make this a special season. Their thinking was that they would show they dominate the B12 and then move to the B10 in short order. That is why the Rising "injury" was such a problem for many. They felt it derailed their plan/investment.
I suspect that their NIL money will be less moving forward than it is this year. The Harlan situation will only make this worse.
