If you are wondering how the Eagles’ pass defense suddenly turned a corner this season, look no further than Week 6, when DeJean, a rookie, stepped into the starting nickel role. From that point on, the Eagles allowed just 4.2 yards per play out of nickel personnel — which, over a full season (minimum 100 plays), would be the fewest since Next Gen Stats began tracking in 2016. That midseason switch flipped Philly from one of the league’s worst slot defenses to one of the best. DeJean’s individual numbers underscore his impact: He allowed only 4.9 yards per target as the nearest defender, lowest among slot corners with at least 30 targets, and the third-fewest by any rookie in our data.
