While it's a nice to idea to get a "pure" pass rusher, I go back and forth as to whether or it would necessarily be so. - Hear me out for a minute. If we picked up Graham for example, and he is shown to be a good NFL pass rusher, would it put too much pressure on the other defenders to cover for this? Can Graham also drop back into coverage? If he can (or whichever perceived pass rusher specialist we draft can), well and good. But if he is a "one trick pony" - just a pass rusher, do we want that?
Opposing teams would be able to anticipate him - knowing that if he is in there is a very high liklihood that he is blitzing, and attack the hole that is created in the defense. If they know he can't drop into coverage very well, they can exploit that as well. I'm talking about good QB's and teams here - the ones we weren't able to sack last year.
I prefer having a defense (and I think Manusky does as well) where the Offense never is quite sure of what the defense is going to be doing. All the players can defend against the run, pass, and also pressure the QB.
Right now, our defense is pretty d@mn good. It's the Offense that needs to improve, both in big plays as well as sustained/possession type drives.
Spend the 2 firsts on Offensive players (unless 1 of the big name defenders falls), and I think the chances for an improved season are much greater.
My 2 cents.
