During head coach Andy Reid’s tenure, he’s built a dynasty and turned the Chiefs into one of the NFL’s powerhouses.
Reid has led Kansas City to a 143-53 record in his 12 seasons, which include 11 playoff appearances, nine AFC West titles, five Super Bowl appearances, and three Super Bowl titles.
But Reid’s success hasn’t been a solo endeavor.
The 67-year-old future Hall of Famer has always had a strong support staff thanks to the top-tier-level of assistant coaches he’s brought in, and one of those assistants has decided to call it a career.

The Chiefs announced on Wednesday that longtime assistant special teams coach Andy Hill had retired after a five-year run with the team, which saw four trips to the Super Bowl and two Super Bowl titles.

Hill responded to the team’s announcement on X Thursday morning.
“Thank you @Chiefs – Coach Andy Reid and Dave Toub and the wonderful coaches and players that I was honored to be a small part of such a class organization-Top to bottom the best in the NFL! Our family says THANK YOU! 🙏” Hill wrote.
With a small hole to fill on Reid’s staff, the Chiefs wasted no time finding his replacement. They also brought back a familiar face to fill another hole on the offensive staff, according to Matt Derrick of Chiefs Digest.
“With Andy Hill’s retirement, Porter Ellett has moved to assistant special teams coach for Dave Toub,” Derrick reported. “Mark DeLeone, former linebackers coach for the Chiefs, returns to KC and takes over Ellett’s old role as assistant RB coach.”

This will mark DeLeone’s third stint with the Chiefs. He previously served as a defensive quality control coach from 2013-2015 and worked his way up to assistant linebackers coach from 2016 to 2017 then inside linebackers coach in 2018.
Kansas City brought him back in 2022 to serve as a defensive analyst, where he stayed until last season when he left to join the rival Baltimore Ravens as inside linebackers coach.
His new role as assistant running backs coach will mark the first time in his 13-year NFL coaching career that he’ll be working with an offensive unit.
