I think it gives about as much insight as you could ask for with the waiver wire. No idea who's gonna be there, no idea which team with higher priority will steal your claim. At this point, what else could anyone say?
"Hammer the waiver wire" is pretty clear to me. They're going to be looking for just about anyone and everyone and will likely put a number of claims in.
I think they'd be foolish if they did anything other than "hammer the waiver wire". The DL has plenty of room to improve upon and they're pretty much trying any combination possible at LB.
Pretty much any defender with experience or who is cut from a team with a strong DL should get a serious look.
