The 1998 Western Athletic Conference Mustangs football team represented Southern Methodist University (SMU) as a member of the Mountain Division of the Western Athletic Conference (WAC) during the 1998 NCAA Division I-A football season. Led by second-year head coach Mike Cavan, the Mustangs finished the season with an overall record of 5–7 and a mark of 4–4 in conference play, tying for fifth place in the WAC's Mountain Division. However, SMU vacated 10 games after Steve Malin was found to have been ineligible due to academic fraud. The Mustangs played their home games at the Cotton Bowl in Dallas. Wiki link
