Are NFL players allowed to help college kids in the offseason?

Seems to me that this is something of value not offered to the general student population, so in principle I would think it is a violation. God help anyone who tries to answer the question with precedence from NCAA rulings.

depends on the type of "help" Im sure

Not sure. Whether they had a pre-existing relationship with the player plays into it too (see some NFL/NBA folks paying for siblings tuition).

What kind of "help"?

If AU is associated in any way with whatever you're getting at, I'll assume some sort of violation is taking place.

I thought about this exact question yesterday when Butch Jones said Peyton had helped his QBs a tremendous amount this summer. It sounds like it would be some ridiculous rule the NCAA would have, but surely Butch wouldn't come out and admit violating it if the rule indeed exists.
