Jim Thorpe became an All-American at Carlisle Indian School in 1911 before going to Stockholm, Sweden the following summer to win the Olympic pentathlon and decathlon and buddy up with King Gustav V. He then returned to become the subject of a massive Nike advertising campaign. OK, maybe the Nike campaign was way ahead of Thorpe's time, but so was Thorpe. In fact, what Thorpe did after becoming an Olympic hero is more impressive. He returned to Carlisle and became an All-American again, captaining the Carlisle team that went 12-1-1 and upset Army, 27-6. Carlisle coach Pop Warner, who would garner 319 victories, called Thorpe "the greatest all-around athlete of all time."
