Kiffin simply stated the obvious.
As for some of the above crying, college football is changing but not dying. NIL and the transfer portal are part of the changes. Some people felt the Olympics would die with the end of amateurism. They did not. Instead, amateurism simply stopped being part of the discussion. The Olympics prosper due to continued viewer interest.
The current changes to college football are belated adjustments to the college football model. Between 2005 and 2015, Power 5 football saw a 266% increase in revenue. Much of that additional revenue went into increases to football coaches salaries and football facilities. By 2015, the 53 Power 5 schools were playing over $405 million to the 530 coaches. Scholarship packages to the slightly under 5,000 football players was just under $180 million. In other words, the coaching salary pool for 530 coaches was 2.25 times the pool for the 5,000 players.
Coaches were generously paid before 2005. I personally believe most of the additional revenue should have gone into reduced increases to student tuition, and economic development and related research increasing economic opportunity for the citizens of Tennessee. University football revenue should be taxed as Unrelated Business Income (UBI) if its sole use is to make head coaches 1 percenters.
NIL is its Wild West phase. University boosters will abuse the lack of rules and scandals will likely happen. Universities should have no role in NIL since they are enablers for booster corruption. Instead, NIL should be managed through group licensing approach on behalf of the athletes.
