The Razorbacks joined the Southwest Conference (SWC) as charter members in 1915. The conference also included teams from Texas (Baylor, Rice, Texas, Texas A&M) and Oklahoma (Oklahoma, Oklahoma A&M). Southwestern (TX) would also join, but leave the following year. The 1916, 1917, and 1919 teams were led at quarterback by "Arkansas' greatest athlete" Gene Davidson. The Razorbacks didn't have a winning conference record until 1920, and didn't win the conference championship until 1936. Arkansas had the best record during the 1933 season, but had to forfeit the SWC Championship because Ulysses "Heine" Schleuter, who had no eligibility remaining, played on the team. Schleuter had told coach Fred Thomsen that he was eligible, but he was recognized by an SMU player during the game as a former Cornhusker. The Hogs did accept an invitation to the 1934 Dixie Classic, a precursor to today's Cotton Bowl Classic. Arkansas became rivals with Ole Miss due to proximity. Although not SWC members, Ole Miss played Arkansas intermittently until a yearly series began from 1952–1961. During the 1938 season, the Razorbacks replaced their 300-seat stadium known as The Hill with Bailey Stadium, named after Arkansas governor Carl Bailey. It was known as University Stadium for one game before being changed to honor the governor. This stadium still exists today, although heavily renovated, as Donald W. Reynolds Razorback Stadium, the current home of the Razorbacks.
