FOXBOROUGH, Mass. — Coaching turnover happens to every team, every year. It’s no different inside Gillette Stadium. What’s different, however, is the amount of coaching turnover Bill Belichick had during this 2019 offseason.

Looking back at every coaching staff Belichick has had in Foxborough, this offseason represents the most change with five assistant coaching departures and six coaching promotions/new hires.

The offseason of coaching change started with defensive play caller/linebackers coach Brian Flores heading to Miami to become the Dolphins head coach. With Flores, went receivers coach Chad O’Shea, cornerbacks coach Josh Boyer and assistant quarterbacks coach Jerry Schuplinski. Next, defensive line coach Brendan Daly left for the Kansas City Chiefs.

That left Belichick with one defensive assistant remaining from his 2018 staff, his son, Steve Belichick. To make matters more interesting, the man they hired to be the defensive coordinator (Greg Schiano) resigned in March.

Was there any worry in Foxborough? You probably know the answer.

“Not really. The great thing was, there’s one guy that leads this ship (Bill Belichick),” said Bret Bielema. “He always has a great direction and great focus. I know from the outside world, you guys don’t have as much (answers) as you want, but from the inside world, there was never a doubt where we’re going.”

Bielema represents one of the six coaches to receiver a promotion this season. (Well, unofficially anyway because the Patriots still haven’t officially announced any changes.)

Bielema, the former Arkansas head coach, spent last year as a consultant on the Patriots’ staff and will coach defensive linemen this season.

Other changes on the defensive staff include Mike Pellegrino working with defensive backs, DeMarcus Covington coaching outside linebackers and Jerod Mayo coaching inside linebackers.

Offensively, Mick Lombardi is expected to become the assistant quarterbacks coach.

The biggest surprise of all is Joe Judge. The Patriots’ special teams coach since 2015 will now also coach wide receivers, replacing O’Shea. He’ll still work with special teams, who also have assistant Cameron Achord.

“It will definitely be challenging,” O’Shea said Friday. “The best thing we have now is very good support. Cam Achord does a tremendous job. We have great assistants on the offense.

“There’s great support from the top on down with Coach Belichick, with Josh (McDaniels). The biggest thing I can do to help the team right now is to stay organized and diligent to make sure I’m taking care of all my responsibilities to help the team. Make sure they are prepared the best they can be.”

The Patriots routinely have developed coaches within their own system. That’s seen Pellegrino and Covington graduate from “coaching assistants” to more defined roles (even if no one will admit their actual defined role).

Other former coaching assistants, who were later promoted include McDaniels, Matt Patricia, Flores, Boyer, Bill O’Brien and Steve Belichick.

“I’ve been working with the (defensive backs) ever since I walked in the building, so nothing’s really changed for me,” Pellegrino said. “The title’s not important to me because my title last year really wasn’t an indication of what I did last year. So it didn’t really matter.”

“Just like we tell our players, just because you play a certain position, your position doesn’t define who you are,” Covington added. “It’s what you make of the opportunity is what defines who you are.

“That’s the same as coaches for us. The title doesn’t reflect the opportunity that I have. I have a great opportunity in front of me and I’m just trying to make the best of it.”

The last time the Patriots had this much coaching change was in 2012 when the Pats technically added six new assistants. But that number was a little misleading because it includes Patricia being given the defensive coordinator title, McDaniels’ return to offensive coordinator and Patrick Graham (defensive line) and Pepper Johnson (line) flipping roles on the staff.

Although there were six changes, none of those coaches were really “new” hires.

For the assistants here now, it’s business as usual.

“I think one of Coach Belichick’s big things is just do your job, worry about the present,” Bielema said. “Take care of today, what you do today affects tomorrow, the same approach we take when we’re evaluating guys. Let ’em come in and set a standard.”
