Giles has spent the past two seasons as an assistant coach at the University of Houston, where he worked with the Cougars defensive line. He joined the Houston staff prior to the 2003 season after spending three seasons at SMU. Giles helped the Cougars to a 7-6 mark and a spot in the Hawaii Bowl in 2003, the first bowl appearance for UH in eight seasons.
"I'm honored and humbled to be asked by Coach Brown to come back to Texas," Giles said. "A lot of people talk about Texas football, but I lived it and know about the passion, pride and tradition of the Longhorns. It's truly a privilege to be able to be in a position to help the program once again.
"Coach Brown taught me a lot when I was getting my coaching career started at Texas a few years ago and I'm eager to work with him again. I've had a chance to talk with Coach Akina, and Coach Tolleson was doing a great job at UT when I was there before, so I think it will be a very comfortable fit. It's where I started and I'm really excited to be back."
"I want to thank everyone at UH for the opportunity they gave me. I grew up as a coach under Coach Briles and I owe a big thank you to him. He was a great man to work for."
After joining the SMU staff in the spring of 2000, Giles tutored a defensive line that developed into a unit that led the Western Athletic Conference and ranked 22nd nationally in total defense (320.1 yards per game) in 2001. He was kept on by new Mustang coach Phil Bennett and remained at SMU for the 2002 season.
Giles was as a graduate assistant coach at Texas in 1999, where he assisted with defensive backs and helped the Longhorns earn a Big 12 South Division Championship, a spot in the Big 12 Championship game and a Cotton Bowl berth.
Prior to accepting a graduate assistant position at UT, Giles coached the defensive line and served as a strength and conditioning coach at Southwest Texas State (now Texas State) in 1998.
A four-year letterwinner at Texas (1987-90), Giles played defensive end and linebacker for the Atlanta Falcons from 1991-93. He went on to play in the Canadian Football League from 1994-97 and helped the Toronto Argonauts win the Grey Cup Championship in 1996.
A three-year starter at UT, Giles earned AP All-SWC honors as a senior when he helped the Longhorns to the 1990 SWC Championship and an appearance in the 1991 Cotton Bowl. Texas was 10-2 and finished the year ranked 12th that year. Giles also helped the 1987 Longhorns to a No. 19 final ranking and a victory in the Bluebonnet Bowl. He led Texas in sacks in 1988 (6.5) and 1989 (7) and finished with 22 in his career (T-No. 10 on the UT all-time list). A semifinalist for the Outland Trophy and two-time GTE Academic All-SWC selection, his nine career fumble recoveries are tied for second on the UT all-time chart. Giles was awarded UTs Tenacity Award twice during his collegiate career.
A native of Palacios, Texas, Giles earned his Bachelor of Science degree in speech communications from Texas in 1991.
