I don't really understand the first set of charts with respect to the run game. The Dolphins are absolutely terrible at running the ball, and until they played two of the worst teams in the league the last two weeks, were awful at defending every week it as well. But the charts seem to say that they're at least average in those respects. One of the many reasons I don't really trust ESPN and PFF.
Hopefully they sigh a veteran LG this off-season. Maybe not the top one in FA but someone who can play at a much higher level than him.
Guards, tackles and centers are all important- it is beyond me how that's a secret to any football team at any level.
