NIL was absolutely a factor in him walking away. That and the modern college athlete in general.
"I want to be clear that wasn't the reason, but some of those events certainly contributed," Saban said of his decision to retire. "I was really disappointed in the way that the players acted after the game. You gotta win with class. You gotta lose with class. We had our opportunities to win the game and we didn't do it, and then showing your ass and being frustrated and throwing helmets and doing that stuff ... that's not who we are and what we've promoted in our program."
"Saban also talked about how the way the college football landscape is changing influenced his decision. He estimated that "maybe 70 or 80% of the players you talk to" wanted to know about their playing time for the upcoming season and how much they would be making in NIL money."
