The worst unit on either side of the ball for the Miami Dolphins is their cornerback group. It's a weak part of the defense, but fans and media alike were told they didn't have to be great. They needed to be serviceable.
Through three weeks, the corners are, well, serviceable. But, unfortunately, they are being put in a horrible position because the front seven, specifically the Miami defensive line, isn't playing like they were supposed to.
Everything with the Dolphins' defense was going to be predicated on how well the team's front could get to opposing quarterbacks, and so far, it's been a failure.
