I don't get it.
Because its so inside run dependent, and a successful one at that, there is soooo much you can do schematically to have a 50 pts offense every game against every team, with that mentality.
The amount of short yardage plays you can have when everyone and their grand mother knows your running up the middle, run flats, (i.e. what we score with Bauman), run that until they stop it.
As a former offensive player, and OC you can scheme up days of yards with this offense with the inside run as the base.
