Dennis Thurman Warriors defensive coordinator is leaning into experience and fundamentals as he enters his third season guiding the University of Hawaiʻi defense. The longtime NFL coach says good things often come in threes, but adds the Rainbow Warriors must put in the work to make that happen.
“Three is usually a good number for me,” Thurman said of Year 3. “I’m anticipating good things. That doesn’t mean they’re going to happen. We have to make them happen.”
Thurman arrived in 2024 and reunited with quarterbacks coach Dan Morrison, his former high school coach and a host during his training days in Hawaiʻi as a two-time All-America safety at USC. Morrison retired after the 2024 season, but Thurman remained the defensive play-caller. He agreed to a two-year contract extension about two months ago.
“We’ve got a young team, inexperienced on defense, not a lot of snaps,” he said. “Six or seven guys we’re going to count on to play major roles for us. We’ve got a ways to go.”
Dennis Thurman Warriors vision shaped by NFL roots
Thurman played nine NFL seasons as a defensive back with the Dallas Cowboys and the St. Louis Cardinals before moving into coaching. He tutored the secondary for Baltimore’s mid-2000s defense built around Hall of Famer Ray Lewis. Under Rex Ryan, he coordinated defenses for the New York Jets for four years and the Buffalo Bills for two seasons through 2016. He later worked with Deion Sanders at Jackson State and Colorado.
Influenced by the Ravens’ aggressive approach and the Chicago Bears’ famed 46 defense designed by Buddy Ryan, Thurman brought a streamlined blend of those concepts to Hawaiʻi. The goal is an attacking scheme that is simple to learn and fast to execute.
“Football is a simple game,” Thurman said. “It’s a simple game made complicated by coaches.”
Film study at the core for Dennis Thurman Warriors
Thurman says the cornerstone of his teaching is rigorous film work. He traces the habit to high school, when coaches broke down 16 mm reels frame by frame.
“If you want to be good at this game, one of the things you have to be able to do is correct mistakes,” he said. “The reason why you tape and film is so you can show them their errors. When you show them, you critique them. They then have to take the information and get it corrected. Otherwise, why tape it?” Players who do not absorb corrections, he added, will find a seat next to him on the bench.
Thurman also notes the difference between coaching pros and college athletes. In the NFL, he said, players focus on whether a coach can help them make money. In college, the challenge is getting players to understand and execute the plan.
Peripheral vision and the big-picture approach
As a former safety with a sideline-to-sideline vantage point, Thurman emphasizes training the eyes. He encourages defenders to expand their field of view beyond the central action, a lesson he once picked up from a baseball coach who advised watching what happens behind the main characters on a television screen.
After practice on Tuesday, Thurman demonstrated by staring straight ahead and narrating activity around him without moving his eyes, from a player raising a hand to someone walking out a gate. The point, he said, is that peripheral vision grows with practice.
“If you train your eyes to see more, you will see more,” he said. Safeties, linebackers and even linemen benefit from what he calls wide vision, which he believes is essential to playing fast within a simple, aggressive scheme.
