Thank Philbin and Coyle for this mess. Philbin inherited a Top 10 Defense with a Top 5 Rushing Defense. But, that wasn't what he and Coyle wanted. They switched schemes and during their first season the run defense dropped in the rankings. In year 2, Ireland swapped LBs and they fell further in the rankings. Let's not forget Philbin getting rid of talented players who he couldn't control. Big, strong CBs were replaced by little "finesse" guys who were pushed around by bigger WRs. After Philbin and Coyle were gone, Tannenbaum should have done something to improve the defense, but he was too busy trading away current and future draft picks for WRs... the only position with depth. It doesn't help that the new DC is looking a lot like Coyle with CBs 10 yards off the line of scrimmage when they should be hitting the WRs at the snap and an inability to stop the run and cover the middle of the field. Philbin and the Front Office built a team mainly filled with non-tackling, non-blocking, non-NFL caliber players and the roster needs to be rebuilt with tough, physical players. There really aren't that many players on the team worth keeping; too many of Miami's starters would be lucky to be a back-up on a good team.
IMO, it's a miracle that they earned a playoff berth.
