Henley has been in the building and while he's been working his way back, he's also watched film from his previous season and on other players as well.
His eagerness to learn has spilled to the practice field as well, as he could be seen this week in practice working on pass rush moves off to the side alongside future Hall of Famer Khalil Mack, Derwin James, Jr., and Bud Dupree.
Henley has taken advantage of every avenue he can.
"That group right there, the names, it's just a bunch of guys who are trying to craft, get better each and every day," Henley said. "Not only do we get better in the moments we're practicing as a team, but when we have individual time and we can get together and help one another."
He later added: "When you see us there, we're crafting, trying to get better."
Chargers Defensive Coordinator Jesse Minter and others on the defense also praised Henley's growth as more of a voice for the defense as well.
Minter said while there are factors that go into becoming one of the leaders, it's something the linebacker has earned and impressed with so far.
"I think leadership comes with production, it comes with experience," Minter said of Henley. "You have to sort of earn the right to be a leader. When you combine how he operates with the type of play that he put out there last year. He's been phenomenal this offseason."
James added: "He's talking more, he's being that leader, he's confident. I feel like the more Daiyan continues to play, the more he continues to lead, it'll be that much easier for him. He's that type of guy."
And it could spell some big things ahead for Henley in 2025.
While Henley kept his expectations for this year to himself, James didn't shy away from placing some lofty goals in what he's expecting from the linebacker in Year 3.
"I feel like he has that ceiling where he can be an All-Pro player," James said. "Not just Pro Bowl, but All-Pro."
