4 matchups to watch for as the Chicago Bears take on the Kansas City Chiefs in Week 3

Matchup No. 3: Matt Eberflus vs. Matt Nagy

This matchup is an extension of Patrick Mahomes vs. everyone, but for a fanbase that isn't mentally well, and hasn't been for a long time, the clash between the Bears' last two head coaches is the purest distillation of that derangement.

Nagy reinvigorated the Bears in his first season as the team's head coach, winning the NFC North before suffering one of the most painful losses in Chicago sports history to the Philadelphia Eagles. It was all downhill from there, though, and Nagy was fired three years later, paving the way for Matt Eberflus to be hired to take his place.

Nagy, who was the Chiefs' offensive coordinator before joining the Bears, is now back in Kansas City in the same position after Eric Bieniemy left for Washington. As noted above, the Chiefs' offense has struggled through two games, but with Travis Kelce not yet at 100% and the Chiefs' receivers failing to impress, it's difficult to put those struggles at Nagy's feet.

Eberflus, who was the defensive coordinator of the Indianapolis Colts before being hired by the Bears, has overseen a defense that has arguably been the worst in the league during his tenure. General manager Ryan Poles attempted to upgrade the talent level on the defensive side of the ball this offseason, but after being carved up by Jordan Love and Baker Mayfield, it's not clear that the addition of Tremaine Edmunds, T.J. Edwards, and Yannick Ngakoue has made any material difference.

If Eberflus was looking for a chance to prove himself, this is the week. Alan Williams may again be missing as defensive coordinator, leaving Eberflus to once again call the plays, and he'll be going directly against Nagy, who, by the time he left Chicago, had become the main object of Bears fans' derision. If Eberflus can find a way to hold down the Chiefs and get the Bears their first road win since a Monday Night triumph at Foxborough last October, it could go a long way towards repairing a relationship with the fans that already appears to be damaged.
