This may sound stupid, and I might be overlooking something, but the Cotchery play got me thinking. If a player is contacted down, and his elbow or knee lands on a player who is laying on the ground, why isn't that player considered down. Cotchery's momentum was clearly stopped and had a patriot (Samuel I think) not slid under him as he was falling, he would have been down. Should they change this rule? Is there a reason this shouldn't be a rule?
