Yep, on the money IMO. The stories match the play on the field and is literally the only explanation for McVay turning on him.
People liking Goff is blinding them - McVay has stuck by Blythe, Reynolds, Everett and others - why? Blythe was a huge reason why we lost a few games, but McVay never said "our center has to block better". Why?
When GZ missed several FGs, he never said "our kicker has to kick better" - why?
We don't know, but when you put the puzzle pieces together, the only logical conclusion is that Goff did, or did not - do something. Whether that's working or whatever.
Then as noted above you have the players reactions to Wolford, and a few in the media (I heard Rappaport brought if up too but couldn't find it) talking about his lack of work ethic.
It fits.
