• Oscar Giles joined the University of Houston as its Defensive Line Coach in February 2024, marking his third tour with the Cougars after previous stints on staff during 2003-04 and 2015-16. The 2025 season will mark his 26th as a college coach and sixth overall at Houston.
• During 25 seasons as a full-time college coach, Giles has helped coach teams to 19 bowl games including a 2005 Rose Bowl Game title, 2006 Rose Bowl Game/BCS National Championship, 2010 BCS National Championship appearance, 2009 Fiesta Bowl title, 2015 Chick-Fil-A Peach Bowl Championship and 2019 Allstate Sugar Bowl title.
• In 2024, Houston's defensive line turned in an impressive showing up front. The Cougars held opponents under 100 yards rushing five times, ranking 21st nationally and second in the Big 12, while limiting the opposition to one or no rushing scores in nine different contests.
• The Cougars limited opponents to 14 rushing touchdowns, ranking 25th in the Power Four and marking a sharp turnaround from 2023 when it permitted 27 rushing scores. UH opponents averaged just 3.9 yards per carry, the second lowest mark by the Cougars in the last seven seasons.
• Individually, junior Carlos Allen led all Big 12 interior defenders with an 84.4 run-defense grade (PFF) while ranking second in the Big 12 and 17th nationally with two fumble recoveries.

• Giles’ defensive lines played a critical role in one of the most dominant two-year spans in Houston history between 2015-16. The Cougars ranked inside the Top 10 nationally in rushing defense both seasons, racking up a combined 75 sacks which ranked as the 10th most in the FBS.
• In 2016, defensive tackle Ed Oliver, who Giles recruited and coached, was named Scout’s National Freshman of the Year. The All-American sparked a Cougar defense which ranked 14th nationally in tackles for loss per game (7.7) during 2016. Houston’s 22 wins during the two-year stretch ranked fifth in the country including a 2015 Chick-Fil-A Peach Bowl title with a dominant 38-24 victory over #9/8 Florida State.
• At Houston, Giles also coached defensive end Cameron Malveaux, who signed as an NFL free agent in 2017 and played for four teams, and Tyus Bowser, a second round selection who played in 89 games and made 23 starts with the Baltimore Ravens from 2017-22.

In 2022, Wyoming ranked second in the Mountain West and 22nd nationally with 2.77 sacks per game as part of its fifth winning season in seven years.
• As Defensive Line Coach at Texas from 2017-20, the Longhorns won four consecutive bowl games and finished ranked inside the Top 25 three times. During the four-year stretch, seven Texas defensive linemen earned All-Big 12 honors. In three of the four seasons, a Longhorn was named Big 12 Defensive Lineman of the Year (2020 – Joseph Ossai; 2018 – Charles Omenihu; 2017 – Poona Ford) with Ossai earning consensus All-America honors. In 2017, Texas limited opponents to just 106.8 rushing yards per game, ranking eighth nationally, including holding the opposition under 100 rushing yards in seven of 13 games. In 2020, his final season with the Longhorns, Texas ranked 23rd nationally in tackles for loss per game (7.3) and produced the nation’s 14th best run defense grade (85.4) according to PFF.

Giles helped develop Orakpo from the 2005 Big 12 Defensive Freshman of the Year into the 13th overall pick in the 2009 NFL Draft. He was selected to four Pro Bowls as part of a 10-year pro career.
• During six of his nine seasons, the Longhorns ranked inside the Top 25 nationally in sacks per game including during 2008 when the program paced the nation with 3.62 per contest. The Longhorns never ranked lower than fourth in the Big 12 in sacks per game and in seven of nine seasons were among the league’s top three.
• In 2009, as part of the Longhorns second national championship appearance in five seasons, the team led the nation in rushing defense (72.36) while ranking fifth in sacks per game (3.0) and eighth in tackles for loss per game (8.0).
