I own a copy of the video game madden 2004..and ive been playing intently for a while now and i understand most rules and what not...but i am not sure if it is just a thing that happens in my video game or something that occurs on the field...the clock will sometimes countdown during the snap and sometimes it is stopped during the snap...if this occurs on the field in real life can someone explain to me why sometimes the clock is counting down and other times its not.
