This should be the colleges’ issue not the NFL’s. If the athletes are academically ineligible then they should not have been participating at the NCAA level.
Problem is there are 2 months between the last college game and the combine, plenty of time to lose academic eligibility with no real possible consequence (it’s hard to get suspended from games that don’t exist).
they aren’t allowed to participate and with no other option they usually end up entering the NFL draft, even if they have little chance of being selected...
