I think the Packers are thinner now at receiver than any year since 2008, especially if you include TE in the picture. And the effectiveness of the passing attack depends on their ability to spread defenses out and expose their weak points. Boykin has been inconsistent, and I haven't yet seen from Adams the kind of flash that Jennings showed in his first year. Adams might turn out to be a really good one, but he looks like he still needs to grow into the position. Behind Nelson, Cobb and Adams the Packers have a bunch of unknowns. I wouldn't be surprise to see GB overpay (at least by their standards) for Cobb given the lack of proven receivers behind him.
