Cook or Laurinaitis could fill immediate needs in GB. Long's a very good player and I wouldn't get too upset if the Packers signed him but he might be the most expensive and the least need. I won't be surprised if he goes to Chicago. Fangio would know him somewhat and he'd be a good fit there.
Cook could be Finley in GB's offense, 10 cent head and all, and he might be interesting as a pairing with the Rodgerses. I'd imagine Sirimans will have some in-depth intel on him.
