The Miami Dolphins announced several coaching changes yesterday, including three promotions and a replacement for assistant special teams Dave Fipp, who was hired last week by the Philadelphia Eagles to be Chip Kelly's special teams coordinator. The team promoted assistant quarterbacks coach Zac Taylor to quarterbacks coach. Offensive coordinator Mike Sherman has also been holding the quarterbacks coach title, working with his Texas A&M quarterback and Dolphins' rookie Ryan Tannehill throughout the season. However, even back in training camp, the Dolphins' stint on Hard Knocks showed Taylor was working more closely with the quarterbacks than Sherman. Under Taylor's direction, Tannehill set team rookie records in passing yards (3,294), attempts (484), completions (282) and he became the first quarterback in Dolphins history to start all 16 of the team's games in his first year in the league. To replace Taylor, the Dolphins promoted offensive assistant Ben Johnson to the assistant quarterback coach position. Johnson is entering his second season with the Dolphins after being named offensive assistant on February 10, 2012. In 2012, Johnson worked with the offense in various roles including assisting with the signaling in the plays to the offense during games and assisted with a unit that finished fourth in the AFC in rushing touchdowns (15) and tied for third in the NFL in fewest offensive penalties (39). The third promotion moved defensive assistant coach Charlie Bullen to assistant defensive line coach. Bullen is also entering his second season with the Dolphins after being named defensive assistant on February 10, 2012. In 2012, Bullen assisted a defense that finished seventh in the NFL and third in the AFC in points allowed per game (19.8). The defense's 42.6 percent of red zone touchdowns allowed was the lowest figure in the NFL. Bullen spent time assisting with the defensive line, which featured two Pro Bowlers, Cameron Wake and Randy Starks.
