Just playing the what-if game here. The brawl after the kneeldown and ensuing penalty stopped the clock and forced New England to run another play, when obviously with 20 seconds left, they would have run out the clock with one kneel. Obviously having to run another play, if something dramatic happened, Seattle could have ended up winning because of their melee. We have the ten-second runoff to avoid this, yet it doesn't allow the clock to run in a situation like this.
