1906, in the first game of the 1906 season, St. Louis faced Carroll College, and it was in that game that Robinson threw football's first legal forward pass to Jack Schneider. Cochems reportedly did not start calling pass plays in the Carroll game until after he had grown frustrated with the failure of his offense to move the ball on the ground. After an initial pass attempt from Robinson to Schneider fell incomplete (resulting in a turnover to Carroll under the 1906 rules), Cochems called for his team to again execute the play he called the "air attack" or the "projectile pass." Robinson threw the fat, rugby-style ball for a 20-yard touchdown pass to Schneider. St. Louis won the game by a score of 22–0. 1906 season St. Louis completed the 1906 season undefeated (11–0) and led the nation in scoring, having outscored opponents by a combined 407 to 11. During the 1906 season, the forward pass was a key element in the St. Louis offense. Bradbury Robinson threw a 67-yard pass, and Jack Schneider threw a 65-yard pass. In his book on the history of the sport, David Nelson wrote, "Considering the size, shape and weight of the ball, these were extraordinary passes." The highlight of the 1906 season was St. Louis' 39–0 win against Iowa. St. Louis completed eight of ten pass attempts (for an average of 20 yards) against Iowa, and four of the passes resulted in touchdowns. On the last play of the game, St. Louis threw a final pass 25 yards in the air to a receiver who caught the ball "on the dead run" for a touchdown. Cochems said that Iowa's poor showing in the game "resulted from its use of the old style play and its failure to effectively use the forward pass", as Iowa attempted only "two basketball-style forward passes." The 1906 Iowa game was refereed by one of the top football officials in the country, West Point's Lt. Horatio B. "Stuffy" Hackett, who became a member of the American Intercollegiate Football Rules Committee in December 1907. Hackett later told a reporter, "It was the most perfect exhibition... of the new rules ... that I have seen all season and much better than that of Yale and Harvard. St. Louis' style of pass differs entirely from that in use in the east. ... The St. Louis university players shoot the ball hard
