The Philadelphia Eagles announced on Thursday evening that they have hired Sean Mannion to be their new offensive coordinator. In just his third year in coaching, at the age of 33, Mannion has already landed an offensive coordinator job. In that respect, his career path has followed a similar trajectory as former Eagles offensive coordinator Kellen Moore, who became the Cowboys' offensive coordinator in just his second year as a coach. Obviously, Mannion doesn't have play-calling experience with this being his first coordinator job, at any level. The assumption is that Mannion will call plays for the Eagles, but that is not yet something the team has confirmed.
