To Dan Campbell's credit, for the 2nd straight season, he either fired or demoted a Coordinator, and ended up getting far greater results the rest of the season combined. In 2021, Campbell removed the Offensive Play Calling from then Offensive Coordinator Anthony Lynn.
Being that Aubrey Pleasant was part of an LA Rams Coaching Staff that got huge positive results from the team's Secondary, it's easy to see why Sean McVay brought Pleasant back to the Rams.
If the LA Rams Secondary has a good overall 2023 season, Pleasant could again be a candidate to be an NFL Defensive Coordinator. Especially, if Pleasant learned from mistakes that he made on the Lions Coaching Staff.
