This is my take.
Yes they can learn from this and become better, but I don't expect it to happen soon.
I started for the first time to see McVay stare and snap (and maybe snap is a harsh word) at Goff when he has come off the field. I didn't notice any interaction between the two last night. But I'm starting to see it.
Yet, when McVay continues to call pass play after pass play his perception of reality smacks in the face of what his mind is telling him.
Goff has shortcomings and always will. He will continue to get better, but he will always have shortcomings. The sooner his older brother (McVay) realizes that, the sooner we can learn from these types of games and become a better team.
