Could the average NFL fan make it to 20 carries in a game??

Of course this will never happen, but for poops and giggles, say you take your average football fan out there. (between the ages of 22-40) and have the coach tell him he's going to get 20 carries as a running back in an actual NFL game. If he can manages to make it to 20 carries then he wins a nice prize(like money, car, etc.)

Do you think it would be possible for the average guy out there to obtain 20 carries before:

1) he suffers a serious injury (concussion, broken bone,dislocated shoulder, punctured lung)

2) after a few carries, the pain and fear is too great (I've read Brett Favre saying the average fan would panic once the pocket collapsed)

2)he actually gets killed. This is not likely, but i saw a game where Ray Lewis absolutely leveled Eddie George, a 230 lb guy and a fairly chiseled specimen. It would be scary to think how hard a normal dude would go down on a hit like that!
