you still play the game, maybe you don't run your trick plays, but you still work to make first downs, and if there so much time remaining in the game you score TDs and then kickoff, so be it. And all the big programs follow that philosophy, they aren't throwing bombs, but they work to continue making first downs, and if a back runs off wild, or a crossing route goes for 30 yards, then too dang bad for the opposing team.
