If you read my post clearly, I said "starting with the end of the Green Bay game." It was after that game where, when asked about Goff being the Rams QB, McVay hedged with the "right now" phrase. This was after a gutty performance by Goff, and one where he didn't turn the ball over as he had in other games and played reasonably well. He wasn't the reason we lost that game as he had been in others previously in the season.
It was not a smart thing to say at the time. I understand emotions were high right after a playoff loss, but a coach has to keep that in check, and he didn't. And given the way the QB situation shook out this offseason, he's goddamn lucky Stafford became available, because we know now Watson was not really an option and there was nobody else worthwhile who was available.
I'm glad he's happy with Stafford so far; it would be a huge problem if he wasn't. Still, McVay, while a great coach, needs to learn some things about PR and working the media, and the fact that for at least the near future many of his comments regarding QBs will be seen as a slight on the one he traded away is, as I said, a perception he earned. Live and learn.
