re: Why would Riley accept the job now?

Those numbers fluctuate year to year.

For instance, OU spent $20M more on facilities and equipment. Schools are constantly updating and expanding facilities and outfitting those facilities and athletes with new equipment. Those costs are not constant year to year. Some years there are major upgrades, and other years the costs are limited to maintenance.

Major upgrades often fall under the budgets of booster groups like TAF, so those costs aren’t always reflected in athletic budgets.
