John Grieshop/Getty Images Marvin Lewis will reportedly end his 15-year run as head coach of the Cincinnati Bengals at the end of the 2017 season. During Lewis' time with the team, he brought the Bengals back to relevance, but his term was marred by an 0-7 record in the postseason. According to ESPN's Adam Schefter, Lewis will leave the Bengals to "pursue opportunities elsewhere" in the league.
