Suh is great at what he does, but building our defense around that was a mistake. Our whole defense is predicated on upfield penetration and disruption, and it's designed to play with a lead. What we've seen too often now is a defense that fails to consistently control gaps, so we get run on. We see a defense that gets taken advantage of by misdirection and counters. We see a defense that too often leaves the linebackers vulnerable in man coverage or too often leaves huge gaps in the zones. And probably the most frustrating given the stated philosophy of our defense, the pass rush disappears way too often.
The Dolphins are locked into a defensive style that hasn't produced results, and on the rare chance that it does, it's not lasting. It's not Suh's fault, but the coaches seem unwilling to change the defensive philosophy at the risk of alienating Suh. Remember when JJ wanted to change the offense but was worried about the potential friction with Marino? That didn't turn out well either.
