‘Metzelaars, 51, spent the past two years as offensive line coach for the Indianapolis Colts. He lost his job on Jan. 17 when the Colts fired head coach Jim Caldwell. Metzelaars worked six years before that as offensive quality control coach for the Colts, and spent a lot of time learning under assistant coach Howard Mudd, one of the most veteran and respected offensive line coaches in the game.’
