In the annals of mankind's sporting history, big performances rivalries are what separate the players who are revered forever by their fanbases from those who simply don the uniform for a time and then vanish into rarely accessed memory. Bucky Dent was an otherwise unremarkable journeyman middle infielder except for the fact that he got the biggest his of his life as a Yankee against the Red Sox. Geoff Hurst had a pretty pedestrian goal scoring rate for England, but he put away three in the World Cup against Germany and now he will never be forgotten (if you knew who he was in the first place).
