Goff and Gurley before and after shows what a positive approach to offensive football can do and how much a coach can elevate a player.
We saw it with Martz as well when players played their very best football because he developed them, prepared them, and created a system looking for success instead of failure avoidance system which ultimately leads to that - failure.
Goff now has opportunity to make plays and the defense is always on their heals. He will do well as would many Quarterbacks in the current Rams system.
