The qbs on the roster are just placeholders until next years draft. The Skins will probably be in the running for at least Matt Barkley if not Andrew Luck. The 2012 qb class looks to be far superior to the 2011 class. Hopefully Shanny and company don't make the mistake of offering anything more than a 7th rounder for Pryor in the supplemental draft if he's deemed eligible.
Honestly though, if Kerrigan is able to make a decent transition to LB, which he clearly has the work ethic to do, and offers a decent pass rush, the defense could be pretty solid. By solid I mean top 20. LaRon Landry's Achilles could be a big problem.
