Almost 100% positive there have been 3 OC's in three years.
Guy after Sig seemed to clash a bit and Hetlet took over play calling with help from eyes in the sky. He coached the Sophs last year and may or may not have called for the biggest head scratch onside kick in history. Ask
@Cross Bones about that one.
Last year was a great guy who has been a long time trusted ally, but being Hetlet's OC can be stressful. He will likely be fine with Sig coming back. Never sure whether Sig was playing with one hand tied behind his back when GW played ultra-conservative defensive minded football in the '12 title game. While GW played to some pretty low scores through '14, '15 kinda woke them up to the possibility of putting up big points. With Brods and a hot QB, they could win shootouts like L'ville.
Last year started kinda slow but HC was a turning point. WR Pierce showed what he could do when healthy in the 1st half against HC but the kids kinda shut down and frittered away a key game. When they reviewed that film I'm sure something clicked. Only thing to stop that offense was a case of the player yips on the big stage vs LA in the semis seven weeks later.
This year, GW has 5 legitimate threats to go yard on any play. They have inside, outside and over the top available assuming kids stay healthy. I think folks might be surprised when GW comes out of the gate hot against MS.
The 2012 team had some monster talent and heart, so not going to compare '17 to that team yet. That has to be earned.
I do know that bringing back 3,500 yards of offense has to be a tantalizing incentive for Sig to want to come back.
