Marist Liufau discusses cross-training, special teams focus, and Von Miller influence in his third Cowboys defensive season

Marist Liufau is entering his third season with the Dallas Cowboys with a mindset shaped by constant adjustment. In an Aug. 27 conversation on the team’s official site, the linebacker described cross-training as a practical approach to staying ready, particularly as the defensive staff around him has continued to evolve. It is also, according to the Cowboys, his third defensive coordinator with Dallas, underscoring how quickly the demands of NFL coaching changes can compound for a player in the middle of his development curve.

Liufau’s perspective reflects a reality for many NFL defenders, especially those building a longer-term role. New defensive coordinators often bring different fit rules, coverage preferences, and assignment language. Rather than treating those changes as distractions, Liufau framed the learning process as part of how he prepares, with cross-training offering a way to broaden his comfort level across situations. The Cowboys’ piece positions this as more than general professionalism, tying it to day-to-day execution and to how a player protects his value when snap opportunities fluctuate.

Special teams, in the team’s portrayal, is not an afterthought for Liufau. The Cowboys highlighted his involvement there as a meaningful part of his job description, which is common for linebackers who are expected to contribute even when the defense rotation is tight. That focus also explains why cross-training matters. If a player can handle multiple looks, and if he can help on coverage and protection assignments beyond his defensive snaps, his weekly usefulness rises even when the defensive game plan shifts.

The interview also referenced Von Miller as an influence, with Liufau pointing to how Miller’s approach has shaped his own thinking. While the Cowboys story does not frame this as a direct coaching relationship or a specific on-field comparison, it places Miller in the same narrative lane as adaptability and preparation. For a linebacker, that usually translates to an emphasis on tempo, reading formations quickly, and understanding how role clarity helps performance, especially when a player is trying to carve out consistent production.

Context matters here. The Cowboys have the kind of roster environment where competition for defensive snaps can be intense, and coaching changes can alter how responsibilities are distributed. With Liufau having already experienced multiple coordinator handoffs in Dallas, his early emphasis on special teams and preparation suggests a plan designed for continuity even when the scheme labels change. The Cowboys’ official framing makes clear that his value is intended to be multi-channel: defense when called upon, special teams by default.

For 2026, the key question is how that preparation translates into measurable impact during the regular season. The Cowboys’ story points to process, not guarantees. What to watch is whether Liufau’s role expands beyond his baseline contributions, whether his cross-training shows up in increased versatility on game days, and whether his special teams involvement remains stable as the staff’s priorities settle into the final form of the season’s plan.
