Re NCwingman: The only scenario where I'd listen to arguments otherwise is if the clock is temporarily stopped and will start on the RFP -- if there is 0.7 seconds on the clock as it's stopped for the 1st down, the offense cannot be set for 1 second after the RFP before the snap AND get the snap off before time runs out.
The rule does not state "after the RFP" the rule 7-2-6 states "After a huddle or a shift, all players of A shall come to an absolute stop....." The rule does not say A has to be set for 1 second after the RFP, in fact with the new 25/40 clock there is no RFP signal. So with .7 seconds remaining, can Team A Legally get off a snap?
