at 4–8. In August 1922, Walker was hired by Michigan Agricultural College, now Michigan State University, as advisory coach of the football team and as head coach of the basketball and baseball teams. In two seasons as the head basketball and baseball coach at M.A.C. between 1922 and 1924, Walker's basketball and baseball teams had records of 20–19 and 20–11, respectively. From 1924 to 1926, Walker served as the basketball and football coach at Drury College in Springfield, Missouri. In November 1924, Walker was hailed by the Chicago Daily Tribune as "Drury's miracle man" when he took "a team of light recruits" and developed them into one of the most sensational elevens in the history of the Missouri Conference." However, Drury's basketball team failed to post a winning record in Walker's two seasons at the helm, amassing a cumulative mark of seven wins and thirteen losses. 1926–1940 From 1926 to 1927, Walker served as athletic director and coach at Loyola University New Orleans. In his one year as the head basketball coach at Loyola, Walker led the team to a 12–6 record, including three wins over LSU. In September 1927, Walker was hired as the head basketball coach at the University of Texas. He remained in the position from 1927 to 1931, compiling a 51–30 combined record during his four-year stint as head coach at Texas. Walker led the Longhorns to an 18–2 overall record and 10–2 conference record during his second season. He was terminated following the Longhorns' 9–15 season in his fourth year. In August 1932, Walker was appointed as the head football coach at J. Sterling Morton High School in Cicero, Illinois. In October 1932, he was dismissed after Major W.P. MacLean, head of the school's physical education department, charged that Walker was inefficient, had been late for classes, had allowed students to take out uniforms and equipment without making a deposit, and had allowed the shower rooms dirty during the football season. Nearly 300 citizens and parents crowded into the school's regular board room to protest the action. Walker was reinstated after the school superintendent issued a report declaring the charges against Walker to be "petty and trivial." Two weeks after Walker's reinstatement, the individual who had made the charges against him was removed from his position at the school. From 1936 to 1940, Walker coached baseball, football and basketball at Wheaton College in Wheaton, Illinois.
