Packers’ Matt LaFleur talks “special” chance to work with brother Mike LaFleur at Cardinals joint practice

Green Bay Packers head coach Matt LaFleur is treating this preseason stretch like a regular test of preparation, even if the spotlight is on an unusual family connection. During joint practices with the Arizona Cardinals, LaFleur said it has been “good” working alongside his younger brother, Mike LaFleur, who is in his first season as Arizona’s head coach.

LaFleur framed the situation in familiar, candid terms. In comments reported by Yahoo Sports, he joked that Mike has been “quick to criticize” some of his decisions, while also emphasizing that the day-to-day interactions have been productive. The point, in LaFleur’s view, is not about sibling rivalry, but about how two coaches operate when they are forced into the same competitive rhythm.

The joint practices matter for both teams because they come late enough in the preseason for coaches to see clearer patterns in how their schemes hold up under live contact. For the Packers, that includes sharpening timing across positions and testing new looks against an opponent that is also installing and refining its own plan. For the Cardinals, the same reps are a way to measure communication and execution in a system led by a first-year head coach.

Mike LaFleur’s arrival in Arizona is a central part of the context here. He brings a background shaped by working in the NFL coaching ecosystem, and the chance to meet another head coach in practice does not just add a storyline. It also places him in direct contrast with a longstanding, well-institutionalized approach from Green Bay, headed by his brother.

Matt LaFleur’s comments also underscore the interpersonal side of coaching, where staff trust and accountability are constant. Even when brothers are on opposite sidelines, the job requires critique, adjustments, and fast decisions. The reported exchange, with Mike described as quick to challenge, hints at the kind of tempo both coaching staffs likely bring to practice.

As preseason work moves toward its final phases, the storyline is likely to shift from the novelty of the brothers to what the joint sessions actually reveal on the field. The practical question for Green Bay is how well its execution and decision-making translate against Arizona’s defensive and offensive sequences. For Arizona, it is whether the coaching message is landing quickly enough to support consistent performance as the regular season approaches.

What to watch next is less about the family angle and more about carryover. Joint practices often serve as an early indicator of how coaches and players respond to problem-solving in real time, particularly in the areas that take longer to synchronize, such as situational football, communication, and adjustments when a plan meets resistance. This is the moment those habits are being built or tested.
