Are we coming to a point where it is acceptable for a quarterback to throw for approximately 140-something yards as long we win?

Throwing a measly 140-yards several times during the season or even almost a half season?

As long we win?

Or will the head coach personally (as we know Harbaugh will instead of calling out his QB publicly) ask the low-yardage passing QB to "raise the bar" by passing for more yardage?

If I was the head coach, I would say, "Hey, while I am happy you are winning games for us, this is the NFL and we need to put you in a position to throw for higher yardage. We have a backup quarterback who is our future and we are expected to nurture his development in making him the starting quarterback eventually. [John Doe], please raise the bar with higher numbers while still winning.

The John Doe is obviously Alex Smith.
