Those include notable players such as TE Anthony Fasano, WR Dexter McCluster and K Ryan Succop. Each of those players played significant snaps for the Chiefs over the past few years. The Chiefs replaced Fasano with Travis Kelce, McCluster with De'Anthony Thomas and Succop with Cairo Santos.
There's also LB Andy Studebaker, who I believe was living in the KC area (because I see him at my local bakery). This must be convenient for him to be back at Arrowhead.
Trick shot QB Alex Tanney briefly spent time with the Chiefs. He's with the Titans now.
The others are DE Ropati Pitoitua, who was a decent player for the Chiefs, WR Rico Richardson and TE Philip Supernaw.
