The Dolphins continue putting together a coaching staff these days, with the most recent announcement that George Edwards, who left the Miami a couple of years ago to join the Gators then the Bills, is back with Miami after he was fired in Buffalo.
Also returning to the Dolphins 2012 staff will be tight ends coach Dan Campbell, special teams coordinator Darren Rizzi and strength coach Darren Krein, all three of whom were on Tony Sparano's staff last season.
Zac Taylor, a former graduate assistant and tight ends coach at Texas A&M under Mike Sherman, joins the Dolphins as an assistant quarterbacks coach.
More hires will be announced in the coming days as the staff is still incomplete.
But this much we know of the current staff: On offense, the hiring of Sherman shows a move toward experience and thus a possible upgrade with the hiring of Sherman.
Not quite as good.
The Dolphins, as we all know, hired longtime Cincinnati assistant Kevin Coyle to become the defensive coordinator. Coyle is no rookie coach. He's been in the profession 35 years and has been in the NFL 11 seasons, the past nine as Cincinnati's secondary coach.
Coyle also served as the defensive coordinator at Syracuse, Maryland and Fresno State during his career.
But he has never been an NFL defensive coordinator. That is fact. So it will be interesting to see how his running of Miami's switching 3-4/4-3 defense does compares to the work well-regarded and experienced Mike Nolan did the past two seasons.
Nolan was granted his release despite being under contract and left to go to Atlanta -- not because he was advancing, but rather because he was unhappy he was not considered for the Miami head coach position while one defensive assistant -- Todd Bowles -- was a finalist and obviously got an interview. Bowles, by the way, also left to become a secondary coach in Philadelphia.
So the replacing of Nolan with Coyle glows in neon as the big question mark the Dolphins must answer. Nolan had served as the coordinator in Baltimore, Denver as well as head coach at San Francisco when he landed the Dolphins coordinator job in 2010. The Dolphins were sixth in scoring defense, allowing 19.6 points per game a season ago.
The Bengals, by the way, yielded 20.2 points per game and finished ninth in scoring defense.
Coyle faces something of a rebuilding job and does so as a first time NFL coordinator under a first-time NFL head coach.
