That's a good point and one that I didn't take to it's logical conclusion. McVay deserves credit for adapting and attacking what the defense was giving. I think the announcer even mentioned that the defense was daring Goff to beat them. Which, overall, Goff did. Rams will need to continue to adjust though and they seem to have everything they need to play whatever type of game that they want.
With a backup LT and stacked boxes, it's impressive to me that they gave up zero sacks. Which, has to be a combination of line play, play calling and QB play. There were a few times that the heat got turned up and the pocket got "dirty" but they all managed to avoid any sacks.
