Good thing we want Nagy to keep running the ball into brick walls. Doesn't he know that running the ball is magical? Just run and the football gods will give you first downs and trophies!! The Honey Bears will return and the Bears of Yore will line the sidelines. It will be wonderful.
(one quibble because I notice these things: He draws the line of scrimmage and then draws where the OLs feet are later in the play. He needs to either use the OLs feet from the beginning or stop using them as a reference. Before the snap, simply because of how the line sets up, everyone's head except Whitehair's is 1/2 a hard off the LOS, and their feet are easy a full yard back. They do get pushed back can't deny that. But by using the LOS as your starting point and then their feet after the snap, he's created a false comparison just to make his point. Just by using where their feet are before the snap and at the handoff point he would make his point better. But it won't look as good on the video.)
