DeVone Claybrooks, a CFL veteran of five seasons, has retired from playing and will be the Stamps’ defensive line coach. Claybrooks played three seasons with the Stamps and two seasons with the Montreal Alouettes including in 2008, when Montreal made it to the 96th Grey Cup. Claybrooks also played in the NFL and NFL Europe and was a member of the 2002 Tampa Bay Buccaneers’ Super Bowl championship team.

Tony Missick returns for his second season as defensive backs coach. In 2011, Missick coached a young core of Stamps defensive backs that helped the team allow the third-fewest yards passing in the CFL. The Stamps defence also led the league in interception-return yards with 423, led by one of Missick’s defensive backs, Keon Raymond. Prior to his time in Calgary, Missick had extensive coaching experience in arena and college football.
