Free uniforms and equipment plus coach/athlete endorsements are the primary reasons why sneakers and other apparel are so ridiculously expensive and marketed as "gotta have" that young kids will literally kill for them.
Cost is independent of pricing. I can buy Colessium brand ASU products cheaper than Adidas.
Once upon a time, coaches like Woody Hayes, Bo Schembechler, and others of that ilk would point with pride to the academic buildings, libraries, labs, and dorms that football built. No more. In all but a few cases, P5 football money goes right back into the football program in the form of platinum plated, diamond encrusted facilities open only to football players, bloated coaching staffs, and obscene coaches salaries. And then, as with ASU, most of them take money from the college general funds to cover operating deficits.
Reality: P5 is corrupt to its core and nobody seems to care.
