Packers G.M. Ted Thompson agreed with a lot of Green Bay fans: He thought Marshawn Lynch could improve the Packers.
Thompson just didn't want Lynch as badly as the Seahawks did.
Pete Doughtery of the Green Bay Press-Gazette reports Thompson was "in on the bidding" for Lynch before Seattle acquired him. The Seahawks ultimately gave up a fourth-round pick in 2011 and a sixth-round pick in 2012 that could escalate to a fifth-rounder.
I agree with Florio that the Packers should have made a play for Lynch, but it's not a devastating non-move. The Packers, like the Patriots, are a matchup-based pass-first team that will use a running back committee. They don't need to feed a back 20 times a game. Brandon Jackson can handle passing downs well and John Kuhn is a solid enough option on running downs.
Certainly the Packers could use more depth at running back and a spark at the position would be nice. But their troubles at running back matter less than finding some offensive line consistency and locating a pass rush outside of Clay Matthews.
