Unless he gets drafted, I think Mills is the only one who could potentially benefit from an extra year. No NFL team gives UFA RBs a true shot unless they’re hurting on depth, and you’d have to land on one of the two teams who did it this year. Jacksonville and Miami.
The emotional aspect of making the NFL is priceless for a competitor, just need to figure out the business aspect. Roughly $200,000 to be a practice player, cut that in half after taxes and fees vs maybe a full season of productivity, start into graduate school, earn NIL income, and *maybe* find yourself in the later rounds next year.
I just don’t see any non-Frost or non-Nebraska guys coming back.
