It’s been a season of constant change for the Miami Dolphins, and that’s remained true right up until the final breath of the season. The personnel turnover began following the team’s Week 4 loss to the Jets in London, with head coach Joe Philbin fired shortly after arriving back in Miami. Tight ends coach Dan Campbell took over as interim head coach, and promptly fired defensive coordinator Kevin Coyle. Offensive coordinator Bill Lazor would join him several weeks later, being fired at the tail end of November. Now, to complete the sweeping out of the old regime, the team fired general manager Dennis Hickey late last night. Hickey had been with the Dolphins for two seasons, joining the team from the Tampa Bay Buccaneers where he had been a major part of their front office for several years. In Hickey’s short tenure with the team, some of the moves he made may have a lasting legacy on the team, and not necessarily in a good way. Two major contracts Hickey pulled off this past offseason may be with the team for some time to come – the signing of Ndamukong Suh to a six-year, $114 million contract, and giving a Ryan Tannehill a six-year, $95 million contract extension. Both players have been disappointments this year, particularly Tannehill. Hickey’s legacy with the draft may not be much better 2014 first round pick Ja’Wuan James played at a decent level as a rookie when manning right-tackle spot, but struggled when he had to play left tackle last year; this year, James only played seven games, missing a majority of the season with injury. 2015 first round pick DeVante Parker struggled hugely in the first part of the season, though he seems to have come on strong since then. The only real successes from the second and third days of the drafts under Hickey were Jarvis Landry and starting guard Billy Turner. Still, of the 15 draft selections Hickey has made (two of them no longer Dolphins), they combined for just 52 out of 225 possible starts in 2015, with James, Landry and Turner representing 31 of those 52 starts. With the team clearly looking to start afresh, Hickey was always at risk of being let go, especially with his underwhelming draft success and even more so his high-stakes gamble on Suh and on Tannehill. Releasing Hickey early gives the Dolphins a full day’s head start over the other teams who may fire their GMs to begin a search for a successor.
