Teams now can hire assistants from other staffs if they make them a Coordinator, similar, to several years ago putting supervisor tags on titles, such as "Assistant Head Coach" you could have many. The NFL should have refined their rule IMO, to Offensive & Defensive Coordinator Titles only, however, now the Rams have lost Aubrey Pleasant as "Pass Game Coordinator" & Andy Dickerson as "Run Game Coordinator" Once this starts happening to Head Coaches that will actually complain, the NFL will again reverse the rule IMO.
