I'd take Perry just slightly over Neal. Its normal to watch entire NFL games without seeing an pass rusher soundly beat a tackle who knows he's coming low around the edge for a sub 2 second sack. The last two or three of them I remember seeing from a Packer have all been from Perry and they seem to be more and more frequent.

I like them both but if one of them is going to be a steal in their second contract I'd guess Perry.
