Clive had a game against a legendary NFL coach- it was before my time, but I seem to think it was Paul Brown. Clive had no illusions of out-coaching Brown, so he decided to try to get into his head.
Just before the game, he called a benchwarmer over to him. "Paul Brown is a genius. He has visualized this game, play by play, and has strategies to counter any possible moves I will make. Therefore, I will make moves that he couldn't possibly have forseen."
What this move turned out to be was having the benchwarmer run out to the huddle, stay for 10 seconds, then get back off the field before the play started. Rush had to be talked out of punting on second down. It was sort of like Bizarro football, with Clive doing everything wrong, on purpose. This strategy is credited with turning the betting line of a 14 point loss into an actual 13 point loss.
This benchwarmer later played for Paul Brown, and related the story to him. Brown recalled the game, and remarked, "I always wondered what the Hell he was doing over there." Rush, incidentally, was later institutionalized."
