Frank Zombo, Brad Jones, Jamari Lattimore, Vic So'oto, Clay Matthews III and add in Erik Walden now? So much for needing to draft OLB!
Walden signing changes nothing, nothing at all. I think Walden or So'oto can be good for the Packers at OLB, but only if they pick up a DE who can give a tinkle of a threat of a pass rush. If they have the same zero production from the DL, it won't matter if they have two Matthews' on the edges.
The DL needs to EAT up blockers and if they can provide a push, you get double digit sacks by your OLB's. No push from the DL, then the OL will bounce block them and snuff out the OLB.
The Erik Walden signing only adds competition, it does not reduce the need for OLB or DE.
