For Alt, it's been a rapid rise since coming in as a rookie last season and immediately becoming one of the better young tackles in the league.
He's shown his strides in his first full offseason as well as coaches and teammates have praised his growth on and off the field.
But his voice has become even more important in 2025 following the season-ending injury of Rashawn Slater as he now moves to the left side of the line and carries a big voice for the rest of the unit and offense.
"You try to," Alt said. "Rashawn is a huge part of our room and he's that voice ... all five of us [starters] and the room, we know Rashawn is a huge voice for us. We just have to pick up that slack."
It's been a similar rise for Henley who, while not a rookie last season, was in his first full year as a starter in the middle of the Bolts defense.
Henley led the Chargers in tackles last season and was a big part of the league's best scoring defense playing in every game.
And after just one season manning the position full-time, he's naturally grown into one of the team's most infectious leaders while wearing the green dot and quarterbacking the defense.
"He's a guy that has certainly earned that role I would say," Chargers Defensive Coordinator Jesse Minter said on Friday. "Another guy that was here a ton throughout the whole offseason. I thought he really started to become that guy towards the middle to latter part of last year. I think the guys saw that."
Minter later added: "Super excited about Daiyan, very happy and proud of him for getting that honor. I think it's a huge honor when your teammates elect you captain."
