Unless he's a Revis or Sherman, that's bullcrap. You do realize The Packers have a crappy pass rush, right? I don't know why fans look at a solid corner like Shields and assume he's mediocre just because his DL can't pressure opposing QBs. It's really simple. If your team has a below average rush, your corners and safeties are gonna appear worse than they are in reality.
I don't want him not only because I believe he's overrated, but more importantly we don't have the money to keep our own guys much less an overpriced CB
