McVay can't do anything about the O line. That's up to Snead. There simply is no offense w/o an O line. And that means the Defense is on the field so long that even greats like AD get worn out.
And lets give credit to the Niners defense. They are very, very good-especially that line. They are also well coached and have drafted well. That game was not even close. If they had a better qb the score would have been much worse than what it was. I would not be surprised if they end up playing the Patriots in the SB.
