"End Run" means a deviation from some standard, settled means, procedure, practice, or norm. There is an implication of surreptitious behavior. The phrase is derived from the American football offensive "trick play" in which a team typically fakes a sweep with nearly all players to one side of the field but hands the ball off to the end (typically lined up well away from the main group of players) who heads across field in exactly the opposite direction of the flow. Generally the defense does not expect the end to get the ball and will not be watching him in this type of scenario. It will often work at most once a game, because once the defense is burnt on the play, they are watching for it.
