Ryan Tannehill has been sacked in the first quarter this season four times, in the second quarter eight times, in the third quarter 13 times and in the fourth quarter a whopping 19 times. He has been sacked 13 times in 103 dropbacks in the fourth quarter with the game within seven points. Not surprisingly, his effectiveness drops in the fourth quarter: two touchdowns, five interceptions, 5.98 yards per attempt, a 56.6% completion rate. Tannehill also runs more in the fourth quarter than other quarters -- 11 carries for 56 yards -- an indicator that many of his pass attempts become emergency pocket ejections.

The biggest cause of Tannehill's escalating sacks appears to be his coaching staff's unwillingness to adjust. Joe Philbin and Mike Sherman are in the denial about the existence of the slot corner blitz; if some defensive back attacks Tannehill from the left, he is almost guaranteed a free shot. Opponents slowly find this and other weaknesses in the Dolphins protection scheme while verifying that the Dolphins running game is a minimal threat. By the fourth quarter, the Dolphins are in constant down-and-distance dilemmas, facing blitzes that evolved to attack their weaknesses, and Philbin-Sherman have no ready countermeasures. So you get games that end like the Panthers game. And the Ravens game. And the Patriots game.
