Why did the Vikes rely on Jackson?

With their destiny in their own hands, the Minnesota Vikings hosted the Washington Redskins Sunday evening and proceeded to go against conventional wisdom by abandoning the No. 1-ranked run game and relying on inconsistent second-year QB Tarvaris Jackson.

The Vikings average of 164.1 yards per game and 5.3 yards per carry, meaning a first down every two rushing plays. The RB duo of rookie Adrian Peterson and veteran Chester Taylor has carried the Vikings all season, but in their biggest game of the season Peterson and Taylor carried the ball just 15 times combined for a total of 41 yards. There must be some reason Coach Brad Childress would do this, but it makes no sense to me to rely on Jackson and his 68.6 passer rating.
