"We are very saddened to learn of the passing of John Clayton," the team said, later adding that their "thoughts are with his wife, Pat, during this difficult time." Many of Clayton's former colleagues fondly remembered the veteran journalist with their own personal tributes on social media.

"John Clayton will be remembered in so many ways," wrote Schefter, 55, "from how he looked after his wife Pat, to the mark he made in reporting, to the standard he set. He dedicated his life to his wife and to football." In a Twitter thread, ESPN senior writer Seth Wickersham said Clayton "took his work seriously ... but not himself." Kirby Lee/Getty "He was one of those colleagues who was not only always eager to help you, but went above and beyond to help," Wickersham wrote on Twitter, later adding in his thread that Clayton "was an incredible husband and proud native of Pittsburgh, with a knowledge of funk that rivaled his salary cap mastery." In another tweet, Wickersham said his former coworker "loved football and loved to share what he learned about it, and how it worked." The writer concluded, "Most of all, he had that John Clayton voice—a weird, geeky, nasally TV voice that was legendary because so many of us grew up hearing it on TV, tuned into SportsCenter for it, and for the lucky ones, later came to know it as the voice of a sweet friend."
