The key to the last Bears defense and the new one under Dennis Allen isn't a lot different than what Vic Fangio did Sunday in helping the Eagles win it all.

Vic Fangio lounged on a white couch with his girlfriend, Kathy Maruyama, nestled to his side in a quieter room across from the main stage at the Eagles’ Super Bowl LIX victory party. The architect of the defensive destruction of Patrick Mahomes and the Chiefs had finally won a Super Bowl after 38 NFL seasons.

With the Super Bowl on the line, Vic Fangio and the Eagles defense limited Patrick Mahomes to the worst game of his career, based on dropback success rate. The best defense in the NFL was dominant against the best QB in the NFL. And the Eagles are Super Bowl champs.
