The thing is that Nublar and Finactic's intuition about Will Allen having serious problems could be right. But CK is right that these guys we're bringing have very little if anything to do with Allen's situation outside of keeping enough corners out there to keep them all fresh. The fact of the matter is if Will Allen has problems, it's not like you can go to the grocery store and pick another one up. Starting caliber corners are quickly moving into QB, defensive end and linebacker world in terms of salary and importance. If Allen is hurt or limited or not himself all season it's not like, "oh, we'll just plug Frank Walker in there. No problem." That's ridiculous, as CK points out.
To me the issue no one's talking about is that Jason Allen has pretty much been moved exclusively to boundary corner, or so he says, and according to many this has really helped his development and helped him thrive at times this training camp (though I liked what I saw from Carroll and Ness more at the scrimmage). If Will Allen is gone, I'm not sure we can count on Jason Allen there. I mean, this isn't a guy with huge mental skills. If you put him somewhere all offseason and training camp, he's not the kind to react well to being moved back inside. At this point the job would pretty much fall to Carroll, and I would be lying if I said I felt even a little comfortable about that right now.
