The Miami Dolphins offensive line has been an absolute train wreck ever since the season started, and there shouldn't even be an argument against the fact that their mediocre play has made a huge impact on the play of Ryan Tannehill and the rest of the offense.
Tannehill averages less than three seconds in the pocket before pressure arrives, which is less than any other quarterback in the entire NFL. It shouldn't be a surprise Tannehill is struggling, not that it absolves him from getting some blame.
But most coaches and NFL experts would tell you - when they're being honest - is that it all starts in the trenches, and the Dolphins have lost that battle on both ends, on defense as well as offense.
