As an Arkansas Razorback fan I remember the games we played against him. Those were some great games and great times. Alzheimers sucks. Rest in peace Darrell. You deserve it.
Sports Illustrated mentioned his retirement with the Razorbacks' coach:
When Royal inherited the Texas football program, it was in such disrepair that Memorial Stadium was surrounded by barbed wire and a chain-link fence with tall grass growing around it.
"I was disappointed," Royal said of his first impression of Texas. "But I felt I could get changes made."
The biggest victory that first season came against Paul "Bear" Bryant's No. 4 Texas A&M Aggies, clinching the Longhorns' first winning season since 1953. Texas went on to have 19 consecutive winning seasons until Royal's last in 1976, when the Longhorns finished 5-5-1.
Royal's last game was a 29-12 victory over rival Arkansas. Afterward, he and Razorbacks coach Frank Broyles announced they were retiring.
Texas and Arkansas had some amazing games, and it was very fitting that he and Broyles retired together.
