This formation does not seem that hard to defend and is probably the reason they run it more when the defense is tired. Pre snap it is confusing and the defender would need to realize how many possible outcomes. However once the ball is snapped they just have to find the direction, once that is determined it becomes only an option between hand off or keep. Realitstically only the QB or one RB could get the ball. In this case as soon as the ball is snapped Abdullah is no longer an option for a run play. The lb can leave him for a safety. If it is not a quick pitch to Burkhead he is out of the play, if it would be a quick pitch the numbers favor the defense (although I could see Burkhead throwing out of this formation). So the option is only keep or give to Green. On this play Yoshi was down field quick so the pass option was eliminated. The D end needed to step up and take on Long, and disrupts the play. A fresh defense flowing to the ball shuts this down, a tired defense craps themselves and watches the the play develop. By that time the wall and numbers are set and the offense wins. Beck used it perfect on Saturday. Overall it was just phone to see some option football. It truly is the best football to watch when it works, and is the reason I am a Husker fan.
