Mike LaFleur and his older brother Matt talk constantly during the season, but the content of those conversations depends heavily on the scoreboard. The Cardinals head coach explained that dynamic during an appearance on The Pat McAfee Show, describing how he keeps in touch with the Packers coach while both are running their own teams.

Sunday offered a clear example. Arizona beat the Chargers 26-14 while Green Bay was losing 39-22 to the Vikings in the same afternoon window, and Mike admitted he was tracking his brother's game in real time.

“I actually did see the score early in the fourth quarter, so you think things are going well, then I went through media and then saw the final, and that was that,” LaFleur said in his guesting. “So there was no crap talking there.”

"We talk all the time. … We each watch each other's tape."

He described the split outcome as the worst version of their weekly ritual. “It sucks. Like I said in my presser, hopefully you both win and then everyone's in a good place for at least like eight minutes and then you move on to the next,” the Cardinals head tactician said. “But when you lose, that's more what you're talking about. So I was kind of asking more questions about what went down and all that.”

The football side of the relationship runs deeper than postgame check-ins. “We talk all the time. We talked a few times yesterday, whether it's just floating ideas,” LaFleur said. “We each watch each other's tape because there are similarities, just like I pop on the Rams, just like I pop on the Niners, just to glance at it to see if there's anything that they're doing that would fit within our players and our scheme.”

That shared coaching tree explains the overlap. Both brothers trace their systems back to the Kyle Shanahan and Sean McVay branch of the modern offense, which is why the Rams and 49ers tape gets the same treatment as Green Bay's.

Arizona opened its season with the win in Los Angeles and returns home to face the Seahawks on Sunday. Green Bay travels to face the Jets, looking to bounce back from a lopsided division loss that gave the brothers plenty to talk about.
