Tom Brady's uncertain future likely will dominate the New England Patriots' offseason.
But there's a more immediate uncertainty that needs to be addressed: The Patriots' coaching staff is very much in flux.
Offensive coordinator Josh McDaniels has head coach interviews lined up with the Cleveland Browns, Carolina Panthers and New York Giants and is a serious candidate to land all three jobs.

Special teams coordinator/wide receivers coach Joe Judge reportedly is drawing interest from the NFL and college ranks, while defensive line coach Brett Bielema reportedly is in the running for an NFC defensive coordinator job.
That's a lot of moving pieces, especially after New England lost a handful of key assistants after the 2018 season.
To make sense of where things stand, below is a rundown of the Patriots' player personnel and coaching staffs, with predictions about whether each coach will be with the New England in 2020.

Nick Caserio, director of player personnel: Caserio's contract with the Patriots expires this offseason, and it's difficult to see him signing a new one. While the Houston Texans reportedly are no longer interested in hiring him as their next general manager, there's a good chance the Ohio native could follow McDaniels to Cleveland to become the Browns' next GM.
Will he be with the Patriots in 2020? No.
Coaching Staff
Bill Belichick, head coach: All signs point to Belichick returning for his 21st season as Patriots head coach, even if (... especially if?) Tom Brady leaves this offseason.
Will he be with the Patriots in 2020? Yes.
Josh McDaniels, offensive coordinator: Brady's future may not be determined until free agency in March, which could complicate things for McDaniels. But after the 2019 season ended, this seems like the year he finally takes his second head coach gig after spurning the Indianapolis Colts two years ago.
Will he be with the Patriots in 2020? No.
Dante Scarnecchia, offensive line coach: Scarnecchia turns 72 in February and may consider retiring again after first stepping away in 2013. If he still wants to coach, though, he has a spot locked up in New England.
Will he be with the Patriots in 2020? Yes.
Ivan Fears, running backs coach: Fears has coached New England's running backs since 2002, and that isn't expected to change anytime soon.
Will he be with the Patriots in 2020? Yes.
Joe Judge, special teams coordinator/wide receivers coach: Judge reportedly is interviewing for the New York Giants' head coach job Monday, but he's also a top candidate to be the head coach at his alma mater, Mississippi State. Both would be significant promotions from his current gig.
Will he be with the Patriots in 2020? No.
UPDATE (Tuesday, Jan. 7, 11:30 a.m. ET): The Giants reportedly are hiring Judge as their next head coach.
Nick Caley, tight ends coach: Caley just finished his third season as the Patriots' tight ends coach, and while he didn't have much to work with, he should be back in 2020.
Will he be with the Patriots in 2020? Yes.
Cole Popovich, assistant running backs coach: There shouldn't be much turnover in the Patriots' running backs room after Popovich's first season as assistant running backs coach in 2019.
Will he be with the Patriots in 2020? Yes.
Mick Lombardi, assistant quarterbacks coach: The son of former Patriots executive Michael Lombardi should be sticking around, regardless of what Brady's future holds.
Will he be with the Patriots in 2020? Yes.
Steve Belichick, secondary/safeties coach: Do you really think Belichick would let another team take his son?
Will he be with the Patriots in 2020? Yes.
Bret Bielema, defensive line coach: Bielema reportedly is interviewing for the Detroit Lions' defensive coordinator position and likely would take it if offered. The former Arkansas head coach may not have many other opportunities, though, so this is a tricky one.
Will he be with the Patriots in 2020? No.
Jerod Mayo, linebackers coach: Mayo could be a dark horse candidate to leave, especially if an old friend like Detroit's Matt Patricia or Tennessee's Mike Vrabel comes calling. It might be too soon for Mayo's departure after just one season, though, and it's possible he slides into the defensive coordinator role if Bielema leaves.
Will he be with the Patriots in 2020? Yes.
Demarcus Covington, outside linebackers coach: Covington was another first-year member of the Patriots' coaching staff in 2019. He'd likely take the linebackers coach job if Mayo left or got a promotion.
Will he be with the Patriots in 2020? Yes.
Mike Pellegrino, cornerbacks coach: The 26-year-old Pellegrino coached up an excellent Patriots cornerback group in 2019 and is a name to watch in the coming years.
Will he be with the Patriots in 2020? Yes.
