NCAA: Illegal forward pass and roughing the passer?

It did occur to me that even if it's not RTP that it could be another PF for hitting a player who's clearly out of the play.

I was just curious as to what might happen if a PF happens after the receiver was down. The defender sort of gives him a little shove but nothing egregious.
