4. Reunited with Herbert
Part of the excitement in coming back to L.A.? Being able to catch passes again from Justin Herbert.
The wide receiver is one of Herbert's favorite targets and has caught 18 touchdown passes from him, which is good for the second-most of any receiver No. 10 has played with.
In the four seasons the two played with another, Williams had 187 receptions for 2,797 yards in 44 games.
"Just the past, everything we've done in the past, the amount of plays we made and having fun out there and celebrating with the guys," Williams said. "Just excited to do it again and looking forward to it."
Williams said he and Herbert stayed in contact throughout last season and even talked to him a couple of days before, as the two are fired up to be together again.
And he doesn't expect too much rust in the connection, as they've played a lot of football and have the chemistry that comes with the experience.
"We played a lot of football together," Williams said. "I feel like he trusts me, he just puts the ball up and I go get it. That's the main thing.
"I feel like we gained a lot of trust in each other over the years and I'm excited just to get back with him, get on the field and starting gaining that connection back and making plays again," Williams added.
His quarterback is the same, but the room he is entering looks quite different than even a year ago.
Williams joins a position group headlined by Ladd McConkey, who broke Chargers franchise rookie records in receiving yards and catches.
He's fully aware of the type of season McConkey had and now as the veteran in the room, Williams said he is looking forward to being a veteran leader just like others were to him when he was younger.
"For me, just being that guy that Keenan [Allen] was to me," Williams said. "Small things in running routes, after catch, blocking in the run game, just small things. Need to watch more film to see where he can improve on when we get together this offseason."
And given the season McConkey had last season, Williams joked he might even take some things from him and try to replicate him.
"I'm going to take things from him," Williams said with a laugh. "He had an awesome season, I had a terrible season, so maybe I need to learn something from him.
"Getting with him and seeing what I can learn from him also and whatever he can take from me, take it," Williams added.
He is also reunited with third-year wide receiver Quentin Johnston, with whom he spent a year with in 2023.
Williams saw the jump Johnston had in Year 2 with a bigger year than the first and is looking to keep that momentum going.
"Q made a big jump from his first year," Williams said.
He later added: "When he first got drafted, met up, told him we all expect greatness… This year, he made plays. Looking forward to building off that and keep going."
5. First time at The Bolt
Some new faces weren't the only thing Williams saw in his return to the team.
The veteran wide receiver also got his first tour of The Bolt, the new Chargers state-of-the-art facility that opened last summer.
It's safe to say Williams came away impressed from the moment he arrived on location.
"Probably the outside of the building, just pulling up to it," Williams said. "It looks nice. The best facility I've been to by far.
"Just pulling up to it, the locker room is nice, everything is nice for sure," Williams added.
It's now the third facility that Williams will spend time as a member of the Chargers, and the veteran joked it's got him feeling like time is going by too fast.
"I got to see three buildings," Williams said with a laugh. "Feeling kind of old though now."
