Yes, the clock starts when the receiving team touches the ball - a play at the end of the quarter or game itself lasts until it is over, not when the clock hits 0.
World champions? Who else plays football? I mean the Canadians, but ... Besides, even the Cowboys could beat any other foreign team, so World Champions is correct. It ain't like the other football where they don't use nothing but feet. But that game is the Seinfield of sports - "nothing ever happens." You watch for a couple of hours and the score is still tied -- 0-0. Then they let them kick balls closer and closer until someone can score. Funny.
