Who is the best American athlete of all time? For now this will just be a thread, but I am thinking of doing a poll once there are enough suggestions. This can be for any sport, just the athlete needs to be American. The reason? Because if we included anywhere else, people would be pulling people that participated in the Olympics 2000 years ago. I think it is quite close between Michael Jordan and Babe Ruth. While Michael Jordan is perhaps the best basketball player ever and most well known athlete in America, Babe Ruth popularized the original American sport of baseball and is perhaps the best baseball player ever. I am going to have to go with Babe Ruth just because not only was he perhaps the best player of his sport like Jordan is, but he also helped pioneer baseball from a low-scoring, pitching oriented game to a more well rounded offensive game too. He changed the sport more than Michael did.
