Last year, goffs mind set was totally different. He came in when the season was basically over, trying to wrap his head around an unnecessarily, over - complicated, yet unimaginative and predictable scheme that had already lacked confidence from the other 10 starters.
brady steps up to the center fully expecting everyone to do their jobs perfectly, including the OC, so when someone screws up occasionally, it doesn't phase him, or the other players. Goff, on the other hand, had to be hoping that any number of common ram errors wouldn't happen.
I like what we're hearing from Jared, his teammates, and the coaches about his confidence and significant improvement of command of the offense. All of this shows his dedication, improvement, and that the rams made all the right coaching moves this off season.
