On average this week, NFL teams rushed for just under 94 yards per game, which is significantly down from the 115.9 yards per game averaged in 2012 and 116.94 yards per game averaged over the last five seasons.
Only two running backs in Week 1 topped the 100-yard mark (McCoy and the New England Patriots' Shane Vereen, who had 101 yards). In fact, before Monday night, it was a quarterback, Terrelle Pryor, who led the league with 112 yards on the ground. Just 11 teams broke the rushing barrier of 100 total yards.
It wasn't just that teams weren't running the ball -- not uncommon in today's NFL. Of those players who did receive more than 20 touches, only McCoy and DeMarco Murray (20 carries for 86 yards) averaged more that 3.3 yards per carry.
Many big-name backs in Week 1 had well under 70 rushing yards:
Even when some numbers didn't look so bad, like Adrian Peterson's 93 yards on 18 carries, there was an undercutting statistic. After taking his first carry for a 78-yard touchdown, Peterson had just 15 yards on 17 rushes the rest of the game, including minus-8 yards the rest of the first half.
Part of it has to do with offenses focusing on the pass. But we shouldn't discount offensive line play. Not only are there some poor offensive lines, but many are built for the pass and struggle to open holes for running backs.
Just how bad was it for running backs in Week 1?
