I'm going with frustration and an off night combination. He had to be wondering what was going on after the first three plays of the game. A third and 8 draw play after two failed running attempts, ole Todd caught them off guard with that call.
I think there might be something to that. If he is busy wondering "what the hell play did he call this time", his head is not into executing the called play. Based on how he has done, it could very well be that Ben does not fully sanction the preferred playlist, therefore he doesn't have that emotional component when he executes.
Crush your enemies, see them driven before you, hear the lamentations of their women.
