An interesting anecdote.
I attended my son's school play this morning. I talked to another dad in the class, who in a former life coached high school football in both Virginia and Georgia. I posed to him the question of whether he had ever seen an offensive line shift before the snap like Furman started doing this season. He told me that he had.
He said that there was one high school team in Virginia that would periodically shift their offensive line before the snap to unbalance the line. Interestingly, he said that the head coach of that team (I don't know who) was a former Furman player from the late 80s.
Of course, both Furman's head coach and OC were on staff with the Paladins in the late 80s. Could be this old school "wrinkle" to the offense has just been buried in the play book for decades.
