That's what makes Grimm such an interesting part of Tennessee's offseason. Aside from the yawn-inducing hire of Mike Mularkey as head coach, Grimm might be the most important decision made by the higherups given how much of the Titans' future is allocated up front. Grimm has been out of the coaching game since 2012, but was a finalist alongside Mike Tomlin to replace Bill Cowher back in 2006. He won a Super Bowl coaching Pittsburgh's offensive line and reached another as the offensive line coach of the Cardinals.
