Nagy has himself a bad night in Chicago Bears home finale

For all the buildup to the first family reunion between coaches Matt Nagy and Andy Reid, quarterbacks Mitch Trubisky and Patrick Mahomes and the Fuller brothers, once the game between the Kansas City Chiefs and Chicago Bears finally kicked off it pretty quickly became a microcosm of the Bears' entire season.

And it wasn't very pretty, resulting in a 26-3 Bears loss to leave them at 7-8 with a week left in the season.

The biggest problem was that after multiple promises to get certain things fixed, Nagy almost immediately began repeating the same things that have haunted him all season.

The Bears came out running with Trubisky getting the first two carries for 5 and 1 yards, Tarik Cohen converted on third down with a 6-yard scamper, Trubisky missed receiver Javon Wims with his first pass and then ran again for 5 yards and scrambled for 8 to set the Bears up first-and-10 at midfield.

But six plays in with a little momentum, Nagy's worst instincts prevailed and he called a student body left with receiver Anthony Miller coming back right on a reverse jet sweep action. Trubisky and Miller botched the short pitch and, while Miller recovered the fumble, the Bears were again behind the chains at second-and-20. The drive was, for all practical purposes, over.

The Chiefs answered with a 15-play, 82-yard drive to a 7-0 lead after they converted four of four third downs, including third-and-18 and third-and-10.

The Kansas City offense is just really good, but on the 11th play of the drive on second-and-4 at the Bears' 22, Mahomes missed running back Spencer Ware on a short swing pass to the right, short but clearly a forward pass and for some reason Nagy challenged the call looking for a fumble, giving away a valuable challenge and timeout with two minutes still left in the first quarter.

Three plays later, from his own 20, Trubisky had receiver Allen Robinson three steps behind the defender 50 yards down the field and threw the ball 3 yards over Robinson's head.

After the Bears went three-and-out, the Chiefs took over at their own 30, and on the second play of the drive a big rush from defensive end Roy Robertson-Harris and cornerback Buster Skrine forced Mahomes to throw the ball away, but Robertson-Harris shoved Mahomes after the throw.

It wasn't even a good shove and until three years ago it would have gone unnoticed. But in today's NFL, it's roughing the passer and Robertson-Harris has to know better.

That penalty set up Harrison Butker, the league's leading scorer, for a 56-yard field goal that he nailed, making it 10-0.

The Bears then drove from their 25 to the Chiefs' 43, where the drive stalled and they punted to the Chiefs' 5.

Eleven plays later, the Bears' defense stopped the Chiefs, setting up fourth-and-4 at the Bears' 43.

There, reminiscent of Week 5 in London against the Oakland Raiders, linebacker Kevin Pierre-Louis, who other than at that moment was one of the Bears' best players on the field all night, was guilty of running into the kicker.

That gave the Chiefs a first down at the Bears' 38.

Six plays later, the Chiefs were in the end zone again and, with 52 seconds left in the first half, it was 17-0, the game for all practical purposes over.

While he only finished with 1 sack, linebacker Khalil Mack spent most of the night in Mahomes face and played his best game in months.

At the end of the day, though, the Kansas City offense is just too loaded for the Bears to take them on without Akiem Hicks, Roquan Smith, Danny Trevathan and Eddie Goldman, who went out on the Chiefs' first possession with a concussion.

But the offense, other than a few sparks in the run game with David Montgomery, basically failed to show up, and while Trubisky missed a few plays, he really never had a chance with what Nagy gave him to work with.

It was an awful way to say goodbye for the season to the Soldier Field faithful.

As players, coaches and fans alike ventured off into the evening, Nagy and his troops had really left far more questions to be answered than they had before kickoff.
