I'm still expecting to see AR's (or a revised 3-5-3-c) that tells us that if we know prior to the snap that either team has more than 11 still on the field, and the snap goes off, that we kill the play immediately. The wording in the "new" rule 3-5-3-c says treat it as a live ball foul only if we don't detect the extra players " .... until during the down or after the down is over", so I'm thinking that we'll see some language calibration in the actual rule to fix that ambiguity.
