NCAA teams are struggling with Covid outbreaks. How does that affect the NFL?

At least NFL players get a paycheck, so I can see it, but these college players get nothing.
I won’t be surprised if a large amount sit out, especially the ones that can declare for the 21 Draft.
I think most of the Ohio State players have signed it. I can see if you're already projected to go high as a Sophmore but a first-year guy on scholarship is going be in trouble. If you don't play, you lose your scholarship.
