Like Hoops said before. Teams are going to start bringing a S into the box to stop the option. Even more so now that the fins have shown the blocking scheme of Clay blocking the DE instead of a LB on the fake. What most people don't talk about is how that 4th and 1 play had a direct QB option as the primary play call. It wouldn't have matter if the DE crashed inside or stayed outside and spied Tannehill because Clay was there to block for him. It really was a great play call by Lazor. Once teams bring that S into the box, Wallace will have his free reign on a defense with a single high S. He can run either a skinny post or a fly pattern and on either of them he will probably be open. Tannehill just has to hit him.
As much as I hate seeing Tannehill run, because of the risk of injury, I love how both of his abilities to throw/run allow Lazor to create/scheme a dynamic offense.
