The Dolphins have made three changes to their coaching staff. The Dolphins had to find a replacement for Matt Burke after he was promoted to defensive coordinator. To fill the void at linebackers coach, the Dolphins have hired Frank Bush, who spent the past four seasons as the Rams linebackers coach. He will also hold the title of assistant head coach.
Bush has 32 years of NFL experience as a player, scout, and coach. As stated above, he has spent the past four season as the Rams linebackers coach. He helped James Laurinaitis record three 100-tackle seasons. Last season he helped Alec Ogletree tally 136 tackles, a career best.
The Dolphins have also changed the title of special teams coordinator Darren Rizzi. The longest-tenured coach on the Dolphins has been promoted to associate head coach (I have no clue what this title means) and will still be the teams special teams coach. Rizzi has been through a lot with the Dolphins and has survived multiple coaching changes.
And last but not least, the team has promoted Chris Kuper to assistant offensive line coach. He served as the team's offensive quality control last season and helped out on the offensive line.
