It's effective with Martinez because there is still a passing threat, even with designed runs. But also, recall the 4th and 3 we were stuffed on. We had ran that play quite effectively a few times already. Martinez on a simple QB sprint away from the trips. This time NW guessed right into it because of the run-favored situation. I know it's hindsight so I wont be critical of it, but rather make the point that this woulda been the perfect time for a PA Pass out of that set, which they had done before with Taylor taking a simple couple of jab steps one way, then dropping into a pass.
