Kelley is so stapled to Spiller that he couldn't even let him work out without joining in. It's possible that this is just checking in with the best available list, or it's possible that this is the precursor to an IR designation for someone lower on the Tennessee depth chart. Nobody signed here would be a real threat to playing time without injuries in front of them. Spiller was released by the Chargers at last cuts this year after Kimani Vidal climbed over him for the RB3 role.
