The Vikings have a D-Line that can pressure the quarter back and feature two defensive ends with 9 sacks each (Allen and Robison). Collins and Smith will have their hands full with these two and may require some help on the edge from Gresham and the running backs.
However, despite the big numbers from the ends, the Vikings only rank 17th with 34 sacks and are a putrid 30th against the pass. While the Bengals do not have the individual numbers along the line that the Vikings do, they are effective as a group and can bring pressure with every lineman on their roster.
Despite only 1 sack in their last 2 games, with the game being in Cincy and facing a line that has surrendered 37 sacks on the season, the Bengals ought to be able to get pressure on Cassel.
The Vikings feature a quality line backer (Erin Henderson) in the middle and Chad Greenway is a stud (121 tackles, 3 sacks, 3 INTs) on the outside. However, the Vikings still rank just 20th against the run and 30th against the pass.
The Bengals have had a very solid performance from their line backers in 2013, lead by Burfict and his league leading 151 tackles. The Bengals line backers will play an important role in keeping Peterson in check, but as a group, the Bengals have the advantage.
