John Boyle, a reporter, shared that Kupp's Pearl Jam shirt comes from a tour that took place before Kupp was even born.

During his official introduction to the Seahawks, Kupp shared, "Being here, the communities that we've been a part of, Yakima, Tri-Cities, Spokane, Cheney, to now be a part of a professional sports team here in Seattle, it feels like a full-circle moment."

Having spent his entire career in the NFC West and having played alongside former Seahawks players, Kupp is no stranger to the organization. His experience comes from playing against the Seahawks at Lumen Field, as well as from hearing about the team from people who have been part of it-including ing game coordinator Jake Peetz, who spent two seasons with the Rams before ing the Seahawks last year.

"The biggest thing is just the people that this organization has brought in," Kupp continued. "That was the selling point that Coach Mike (Macdonald) brought, that John (Schneider) had talked about; it was about the people. All the players I talked to, just the culture of this organization, the winning culture of this organization, that's something I wanted to be a part of."

He added, "It's that culture, it's a culture of winning. For a long time, the 12s have made this a renowned environment to play in. It's always something you prepared for when you came up here. It was my favorite thing walking out of the locker room and breathing the Northwest air. It's like, 'Man, this is just a special place to be.' You go out there and you've got the fans creating such an electric environment. They've always been cheering against me, now I get to be a part of that."
