This theory is confirmed when further examining some of the prop bets for this week. While the over/under for the total yards gained by the Arizona Cardinals has been placed at 350.5, the over/under for their yards per carry is sitting at a slightly embarrassing 3.9.
The Bills have given up an average of 5.7 yards per carry on the season while allowing an NFL-high nine rushing touchdowns on just 151 attempts. But with backup running backs LaRod Stephens-Howling and William Powell expected to carry the load Sunday, it seems like the gambling world doesn't see Arizona having much ground success.
Stephens-Howling and Powell have combined for just 24 yards on nine carries in 2012. That's good for an average of 2.67 yards per carry, so it seems like the already insulting over/under might even be a little generous.
