While it is the end of April, decisions are going to be made sooner than later as to how to handle college football 2020. A delay of months or until early next year would have a gigantic impact on players. The only thing certain now is how uncertain everything is.
Who would be eligible for this process? To be declared eligible for the supplemental draft, a player must file a petition, which is reviewed on a case-by-case basis. Normally, it relates to people who lose eligibility after the NFL Draft. However, any delay in the college football season due to the pandemic would have an instant impact on players who would have been eligible for the NFL.
Hadn't thought of this before but it's a really interesting subject. I wouldn't be at all shocked if some prominent names put their names into it.
