5. New England Patriots
Like the Steelers, the New England Patriots are another team that could decide to part ways with a longtime head coach after the 2023 season.
Bill Belichick is one of the great head coaches in the history of the NFL, but the Patriots are currently in the middle of their worst season in over two decades, and the team hasn't won a playoff game since 2018.
There have been reports and rumors floating around that New England has already decided to move on from their longtime head coach at the end of the 2023 campaign, and if this turns out to be true, Brian Flores would likely be a candidate for the vacancy.
Flores began his NFL coaching career with the Patriots in 2008 as a special teams assistant, and he wound up remaining on Belichick's coaching staff until he was hired to be the Dolphins' head coach in 2019.
Flores is someone who has both head coaching experience and experience as a member of the Patriots. This is something that most of the other candidates for the potential job opening won't be able to offer.
If New England finally decides to end the legendary tenure of Belichick in 2024, the team hiring Flores as his replacement makes a lot of sense.
