I’ve been looking forward to getting to this post as I think it really brings us full circle in this series when talking about the philosophy and evolution of the Eagles run game. We started this series by talking about why the Eagles run so much out of the shotgun formation. The reason is arithmetic by nature. By running from Shotgun, the offensive line can leave a backside edge defender unblocked thus gaining a blocker on the playside. Furthermore, because the QB is in shotgun he can “read” that unblocked defender and make a decision that always makes the defender wrong. If he collapses down on running back, the QB keeps and runs through the spot the edge defender vacates. If he stays put to protect the backside he hands off and the Eagles getting a blocking advantage on the playside. Of course this advantage and philosophy only goes so far when you have a QB who isn’t really a major threat to run.
