I wondered if Calvin Johnson had some interest in hitting the market next year as an unrestricted free agent, but I'm sure the Lions had no interest in that one.

Chargers Free Agency 2012: Robert Meachem Agrees To 4-Year Deal - SBNation.com. I like this move for the Chargers. His stats should get a little bump with more playing time, and Philip Rivers will help him look good.

Meanwhile in Seattle: Matt Flynn's First Free Agent Visit Will Be In Seattle - SBNation.com. But not before they meet with Chad Henne.
And I'm not sure why the Vikings are interested in TE John Carlson. But, inexplicably, he's being pursued by multiple teams.
