John Clayton, the veteran N.F.L. reporter who was nicknamed the Professor and who was noted for his detailed insights about teams, his football analysis and his concise game recaps for ESPN, died on Friday. He was 67.
Mr. Clayton died at Overlake Medical Center in Bellevue, Wash., said Mike Sando, a senior writer for The Athletic who was a friend of Mr. Clayton’s for decades.
Mr. Clayton died “after a battle with a brief illness,” according to a statement from the Seattle Seahawks, who confirmed his death. He worked in the final part of his career as a sideline reporter for the team’s radio network.
