Touchdown pass

First legal pass
Most sources credit Saint Louis University's Bradbury Robinson from Bellevue, Ohio with throwing the first legal forward pass. On September 5, 1906, in a game against Carroll College, Robinson's first attempt at a forward pass fell incomplete and resulted in a turnover under the 1906 rules. In the same game, Robinson later completed a 20-yard touchdown pass to Jack Schneider. The 1906 Saint Louis University team, coached by Eddie Cochems, was undefeated at 11–0 and featured the most potent offense in the country, outscoring their opponents 407–11. Football authority and College Football Hall of Fame coach David M. Nelson wrote that "E. B. Cochems is to forward passing what the Wright brothers are to aviation and Thomas Edison is to the electric light."
