Philadelphia Eagles head coach Nick Sirianni has the best winning percentage of any coach in franchise history (.702). He's led the Eagles to the playoffs in each of his four seasons, including a Super Bowl appearance in his second. And now, Sirianni has Philadelphia on the doorstep of a second Super Bowl berth, something no other coach in the team’s history has done.

Yet only a few months ago, despite this success, Sirianni appeared more likely to lose his job then lead the team on another deep playoff run. Questions around his job security began at the end of last season. The Eagles started 10-1, a nice bounce back from its Super Bowl loss to the Kansas City Chiefs a season before.
