First, Clark isn't on the payroll.
Troy will probably be extended so he can retire a Steeler.
Troy is not past his prime as evident by this past season, IMO.
Sign Clark for low?
Why?
He is done, nothing left in the gas tank, don't waste the cap space.
Delmas OTOH is 27 and although previously injured could be the type of player we got like when we signed Clark.
