I don't think it's that much of a question mark. We've got at least 2 known good pass rushers on the line in Daniels and Jones. Guion can pass rush as well and I think he might see him playing at DE where I think he fits pretty well. Raji at nose is an unkown, he's shown the ability to do it from that spot at a high level but after 2013 who knows what we'll get from that guy. Peppers/Matthews are a great duo at LB and Neal/Perry are very good depth there. That's without even counting on guys like Pennell and Elliott to step up and add something. You could even throw in Burnett who plays well close to the line and can get to the QB on occasion. I think I also read somewhere that Randall had a good amount of success in college pass rushing too, he's someone to watch out for if he wins that Slot/Nickle CB spot.
I think we'll be good in the pass rush department. Whether we'll get some consistency stopping the run is the real question.
