HERFORDSHIRE, England (KARE/KTTC) -- After a 78-yard touchdown run on the offense's first play from scrimmage to start the regular season, the Vikings running game hasn't been able to dominate its opponents since.
Adrian Peterson is still racking up respectable yardage, but the Vikings offensive line will be the first to tell you, they have not been satisfied with their overall performance this season.
The pass protection hasn't necessarily been stellar either, as evidenced by the rib injury suffered by Christian Ponder the team's starting quarterback.
"It takes all five guys operating at once. We're not far off, but that doesn't count for much. Wins are what counts", says center John Sullivan.
This weekend, they'll try to find their way, when the Vikings play the Pittsburgh Steelers at Wembley Stadium in London.
