While his status is unknown at the moment, this could be a huge help to the Vikings on Sunday night against the Bears. According to the SBnation(http://www.sbnation.com/nfl/2011/10/12/2485421/julius-peppers-injury-chicago-bears) article the sprain is thought to be serious, but is not totally known yet. He could be out for the game or he could be hobbled. Either way it helps us A LOT in protecting our QB this weekend. Mckinnie had a serious issue slowing this man down, and I can't even imagine what he would do to Charlie Johnson.
Couple this with Cutler's O-line being horrendous and earlier in the season he was the most hit QB in the league, we can only be optimistic about our chances this weekend. With teams changing blocking schemes to account for Allen's beastly knack for getting to the QB and Robison wanting to impale someone too, I hope we can take advantage with this and Pagac can set up some delay blitzes right up the middle with Greenway or E.J. Henderson to work into his blitzing scheme.
Also stack a little bit of Aromashadu and Berrian(who we all hope doesn't play, but has shown glimpses against the Bears) playing their former team, wanting to prove a little something, and we could have ourselves a barn burner.
