According to the ESPN Fantasy Football Guide, the Vikings play all but just 3 games on artificial surfaces. 13 of their games are on turf: 8 at home, 5 on the road against Cincy, Atlanta, the Giants, Detroit, and Baltimore. In case you’re looking at the running backs or the wide receivers from this team (you are, aren’t you?)… Several other teams are close (basically any team that has turf at their home stadium), but I think the Vikings have the most extreme tilt.
