Coaching has a lot to do with his improvement, but he also improved on his own over the offseason by working to get better. Don't strip away the players effort. You can have Great Coaching and a player who has a poor work habit/effort and there will be no improvement.
I agree with that. I think it's a good point.
PLUS Goff had an especially steep hill to climb because he played in a variant of the Air Raid offense. To use hyperbole for fun, the Air Raid infamously kind of anti-prepares qb for pro style play.
In short, Air Raid system qbs are further behind than most.
