What is the rule when breaking the huddle with more than 11 players. If I am interpreting what I read correctly, as long as the replaced player(s) run straight off the field there is no foul? What would make this a foul? I've read a 3-5 second allowance is sometimes used. Also if a no huddle team subs and the replaced players do not get directly off the field does that become a foul at some point prior to the ball being snapped? This is more for my own curiosity, not really anything I have seen. TIA
