Rivera makes ‘very difficult’ decision to fire defensive line coach Sam Mills III

Washington Commanders head coach Ron Rivera made a coaching change on Tuesday morning, firing defensive line coach Sam Mills III.

Rivera cited a “difference in philosophy,” and said assistant defensive line coach Jeff Zgonina will take over. Zgonina has spent three seasons on the defensive staff with Mills and played in the NFL for 17 years.

Week three of training camp is an odd time to make such a move, and Rivera didn’t elaborate much on it: “Just some observations … I just felt it was a change that I needed to make,” he said.



Mills spent the weekend in Canton, Ohio, where his father was posthumously inducted into the Pro Football Hall of Fame. He began his coaching career in Carolina, where he spent 15 years, nine of them with Rivera.

Mills was hired in D.C. in January 2020. The defensive line was supposed to be one of the better ones in the league, but the results haven’t been there.

Washington had 47 sacks (sixth in the NFL) and 78 tackles for loss (seventh) in 2020, Mills’ first season as defensive line coach.

Both numbers decreased substantially into 2021, and a defense that was viewed as a strength coming into the year finished eighth worst in the NFL with 434 points against and fourth worst with 4,333 passing yards allowed.

Rivera cited his history with the Mills family and called the decision “very difficult.”

“I’ve known Sam a long time and he’s a very good football coach,” Rivera said. “I really appreciate everything he’s done. He helped us win a division our first year and things got tough last year, but there’s some things that I felt I wanted to change.”

There was tension among the group last year, when Jonathan Allen and Daron Payne had to be separated after throwing punches on the sideline in Dallas. Then, this offseason, Matt Ioannidis was released and Tim Settle departed via free agency.

“At the end of the day, it’s sad,” Allen said. “I think me and Coach Sam were getting along really well. We were really making some progress as a defensive unit. It’s the NFL. People just got to remember: It’s a great game, but a terrible business.”

Allen said he was surprised by the move, especially the timing.

“One thing I’ve learned in the NFL is that nothing is unusual,” he said. “You have to learn to expect the unexpected and as soon as you get comfortable, the NFL will surprise you. Going into my sixth year, there are very few things that will surprise me in the NFL.”

Allen also said that not much should change in the defensive line room, because Zgonina has been with them for the last three years and the players know what to expect.
