The Kansas City Chiefs are reeling after losing their fifth one-score game, 22-19 to the Denver Broncos, to fall to 5-5 on the season.

It has been a wildly uncharacteristic season for the Chiefs, a team that always dominates in one-score games. To lose all five that they have been involved in feels so bizarre.

Quarterback Patrick Mahomes has played like a Most Valuable Player candidate through 11 weeks this season, but he can only perform so many Houdini acts to help his team win.

The defense has been solid besides not getting as much pressure on quarterbacks that unit would like to have, and they have kept the Chiefs in games.

The biggest takeaway from this year thus far is the running game isn’t carrying their load and is holding Kansas City back in the long run (no pun intended).

ESPN’s Nate Taylor described what has gone right for the Chiefs offense, what has gone wrong and the key to second half success.

What has gone right?

“In his 27th season as a head coach, Reid has largely made the right decision to trust quarterback Patrick Mahomes and be ultra-aggressive on fourth down, especially by his usual standard,” Taylor wrote Monday. “Entering Week 11, the Chiefs had converted 16 of their 20 fourth-down attempts, a key to the offense's success.”

It really is a shocker that the Chiefs aren’t better than 5-5. Great teams convert 80 percent of fourth-down attempts.

What has gone wrong?

“The Chiefs still haven't figured out a way to get more production from their trio of running backs in Isiah Pacheco, Kareem Hunt and rookie Brashard Smith,” wrote Taylor. “Hunt has been most effective in short-yardage situations, but the Chiefs should lean more into screen passes for Smith, who offers the most dynamic ability in the group.”

Ultimately, this position group could be the demise of the Chiefs. Isiah Pacheco is dealing with a knee injury, Kareem Hunt is decent but not a No. 1 and Brashard Smith is just a rookie finding his footing. I bet Kansas City is regretting not trading a third-round pick for New York Jets star RB Breece Hall.

The key to the second half is keeping receiver Rashee Rice and tight end Travis Kelce heavily in the mix.

“Rashee Rice has looked like a No. 1 receiver since he returned following his six-game suspension,” Taylor wrote. “The offense should be built around Rice and tight end Travis Kelce, who is having a nice season at age 36. If Rice and Kelce can be consistent and effective, Mahomes should have more opportunities to hit deep passes to receivers Xavier Worthy, Tyquan Thornton and Hollywood Brown.”

The Chiefs will host the 8-2 Indianapolis Colts in Week 12.
