Stephen Ross might not desire a defensive mind, but Mike Zimmer's impressive resume is overwhelming, and it persuaded the Dolphins to interview him this past week.
Zimmer served as the Cowboys defensive coordinator from 2000-2006 (Jeff Ireland was also with the Cowboys for the latter part of Zimmer's tenure), and Dallas' defense annually ranked amongst the league's best. In fact, they finished the 2003 unit as the NFL's best defense.
After a one-year stint in Atlanta, Zimmer became the Bengals defensive coordinator in 2008, where he has compiled his best work. Cincy's defense ranked seventh in the NFL in 2011 and fourth in 2009, anchoring the team to a pair of playoff appearances.
Zimmer is the most qualified coordinator currently on the market, but it's tough to envision Stephen Ross hiring a defensive-oriented coach. Still, though, expect Zimmer to be one of the likeliest candidates for the job and don't be surprised if he is eventually hired.
