I would hope that if it happens there would be something like a trust developed and nothing was paid out unless the following were met:
1. The student/athlete actually graduates from the same university he played for.
2. The funds/payments are paid out over a specific time frame5 years, 10 years, etc.
3. The student/athlete stays clean. No criminal record, no drug convictions, etc. If convicted felon, payments go into a non-profit or back to the University.
4. No funds paid until the athlete has been out of the NFL for a minimum of 5 years or more.
5. If an athlete takes more than 4 years to graduate he must pay the University back for 100% of the hours in excess of 4 years.
6. If athlete has fathered children he must support those kids-child support.
