Rewind back to the 2021 and 2022 seasons when Jonathan Gannon was the defensive coordinator of the Philadelphia Eagles. Gannon had done some impressive things in that role, with the Eagles allowing the second-fewest overall yards in that 2022 season.
The Eagles' efforts that year were good enough on both sides of the ball that the team reached Super Bowl LVII where, as we know, they fell to the Kansas City Chiefs in a classic shootout. It didn't matter that Gannon's unit had thrived for the majority of the season because, on the biggest stage and under the brightest of lights, he folded like a cheap lawn chair.
