[2] Prior to that, Bobby Grier spent several years with the New England Patriots, where he served in various roles, including as the running back coach, director of pro scouting, and vice-president of player personnel.
In his first 15 years with the Dolphins (before becoming their general manager in 2016), Grier worked alongside head coaches Dave Wannstedt, Nick Saban, Cam Cameron, Tony Sparano, and Joe Philbin.
On December 31, 2018, Grier dismissed third-year head coach Gase and demoted fourth-year vice president of football operations Mike Tannenbaum as part of many organizational changes the team made following the 2018 season.
On February 4, 2019, a day after Super Bowl LIII, Grier hired long-time New England Patriots' assistant Brian Flores as the team's new head coach.
On January 10, 2022, Dolphins' owner Stephen M. Ross fired third-year head coach Flores due to the latter having a bitter relationship with both the front office and the roster.
