The Minnesota Vikings have been struggling mightily in the passing game. Through 4 weeks of the 2015 season, they are ranked #31 in passing yards per game (165.2), #29 in passing first downs (39), tied for last in passing touchdowns (2), and #28 in fewest sacks allowed.
Much of that can be attributed to the crazy number of injuries on the Vikings offensive line to this point. Not only are they without their starting right tackle Phil Loadholt who they lost for the season, but they also have center John Sullivan on short-term injured reserve for a nagging back injury.
