3. Greg LeMond (1986, 89-90)
LeMond was the first American to win the Tour in 1986, leading to two decades of strong U.S. showings. The LeMondster unseated teammate Bernard Hinault as the alpha male of the peloton in 1986. He missed the next two Tours after a turkey-hunting accident in which his brother-in-law shot him with a shotgun. He came back to surpass Laurent Fignon on the final stage in 1989, erasing a 50-second deficit, and similarly beat a 5-second deficit in the final time trial in 1990.
