Colts signed QB Chandler Harnish, OG Zach Allen, C Thomas Austin, LB Alan Baxter, CB Marcus Burley and TE Martell Webb to reserve/future contracts. The "Mr. Irrelevant" of the 2012 draft, Harnish was released at final cuts last August. He'll be a long-shot to crack the 53-man roster in 2014. Austin appeared in one game for the Colts this season.
