The Minnesota Vikings emerged from the first phase of free agency and then the draft, still missing a starting linebacker. Then the Green Bay Packers let Desmond Bishop go, and the solution seemed so obvious. The Vikings announced Thursday the signing of Bishop to a one-year contract, three days after he agreed to terms on his deal. He's the latest to leave Green Bay for Minnesota, joining prominent players like wide receiver Greg Jennings, safety Darren Sharper, kicker Ryan Longwell and of course quarterback Brett Favre to recently switch states in the post-prime stage of their careers.
