Of note, two Texas quarterbacks, Manning and Quinn Ewers ($1.9 million), rank in the top 10 for NIL. Also, while the NIL industry is worth an estimated $1 billion annually, according to NIL company Overdorse, On3's tracker lists only 22 athletes nationwide worth $1 million in NIL valuation. And college football reporter Ross Dellenger has reported that the average Power 5 football player makes about $10,000 to $50,000 through NIL collectives.
