The Facts: Clay has had chronic knee trouble since joining the Buffalo Bills as a highly paid restricted free agent in 2015. The problem has persisted during the team's current offseason workouts, and it is something that HC Sean McDermott is worried about. "We are concerned with Charles' knee situation," McDermott told reporters Thursday. "It's something we have to manage moving forward in order to have him on the field for us, which is important moving forward. He's a weapon for us."
Diehards Line: McDermott did say that Clay has taken part in drills, but the team is being cautious about how much work he receives. The coach added that the impending signing of free-agent tight end Gerald Hodges and Wednesday's signing of free-agent tight end Wes Saxton was not related to Clay's knee issue. Besides Clay and Saxton, the Bills have five other tight ends: Nick O'Leary, Blake Annen, and rookie free agents Jason Croom and Keith Towbridge. ... Clay is a viable TE streamer and a reasonable DFS play when he's on the field. But investing in him as a front-line weapon is no longer an option.
