Warner was the rock upon which Cornell built one of the best lines in the nation at the turn of the 20th century. He was hailed as a workhorse guard who rarely missed an assignment. He was a two-time first-team All-America selection, earning the honor in 1901 when Cornell went 11-1, and again in 1902. Warner was captain of the team as a junior and senior. Upon his graduation, he became the head coach at Cornell for the 1903 season, and his team opened with six straight shutouts and finished the campaign with a 6-3-1 record. Warner later coached at Colgate, North Carolina, Oregon, St. Louis University, and the Sherman Indian School at Riverside, Calif.
