Mack’s return means a pillar of leadership and work ethic will remain on defense as the Bolts transition to a new defensive coordinator in Chris O’Leary.

Mack is perhaps the most respected player in the entire locker room, something he has earned from both his play and ability to guide young players along.

He had an hand in developing Tuli Tuipulotu’s growth but also worked behind the scenes to encourage Tarheeb Still and others to put in the required work in the offseason.

And Mack isn’t afraid to speak up when needed, just as he did on a short week in late October before a Thursday night home game against the Vikings.

With the Chargers sitting at 4-3, Mack lit a fire under the Bolts that inspired a dominating 37-10 win over Minnesota and sparked a streak of seven wins in eight games.

“When guys like that talk, everybody listens,” Tuipulotu said. “Especially if he’s not the type to talk a lot, whenever he talks everybody listens.

“We all buy into what he says because he’s done great things in this league,” Tuipulotu added. “He knows what needs to be done.”

As Mack enters Year 13, it’s clear that he’s taking his career on a year-by-year basis at this point. But it’s worth pointing out that he’s now going into Year 5 in Southern California, longer than any of his previous NFL stops.

By returning to the Chargers, he is signaling that believes his best chance to win is with the Bolts.

Now it’s up to Mack to help lead the way to accomplish those goals, which surely includes elusive playoff success.

And it’s up to the Chargers to keep making shrewd moves in free agency ahead of the 2026 season.
