The rapid explosion in "QB breakdown" videos this year from QBSchool, Kurt Warner, Brees, Daniels and a million copycats made me realize that they seem to have their own name for basically every route combination. "Oh yeah, I call this one Jimmy 2 Shift" proceeds to draw out the route combination.
I get that there are definitely some broad differences like Shanahan offenses leaning on zone run and bootlegs but it's not like they're running some extra special sauce right? Seems like everyone else knows the same plays and could just run more of them if they wanted to have a "Shanahan offense".
What is it that actually separates the quality of these different coordinators and schemes?
