out of the 7 HC hirings
3. Dirk Koetter, Tampa Bay Buccaneers: Tampa's bid for "continuity" made more sense than other teams. They feared losing Koetter to the 49ers and did not want to disrupt Jameis Winston's development with a new offensive system. While Lovie Smith never got a true chance to implement his defensive vision, there's no denying the Bucs got much worse defensively after firing Greg Schiano. The Bucs have a few defensive cornerstones and there is a legitimate belief that Smith's defensive principles no longer work in 2015.We rank Koetter high in part because of his defensive coordinator hire. First-time head coaches often struggle to build a staff, but Mike Smith is a solid, proven coordinator who can handle that side of the ball.
