In key clock situations, the coaches should be reemphasizing to Tanny "do not take a sack, throw the ball away" or "do not throw the ball away, just go down if you have to." That is coaching, pure and simple.
It would help if the play called for a roll-out and not a straight drop-back. On the second sack (the one that took us completely out of fg range), Tannehill was still between the tackles with THREE defenders through. No way to scramble and you really didn't see the play if you think he could have safely thrown it away (without getting an intentional grounding penalty).
