Marshawn Lynch.
The Packers were very high on Lynch in the 2007 draft if I recall. Had he been there, I think the Packers would've selected him rather than Justin Harrell.
Lynch has fallen out of favor in Buffalo and is definitely available. Probably wouldn't take anything more than a 5th round draft pick to get him.
This week, Green Bay gets Buffalo. Certainly, the Bills aren't going to move Lynch to a team they're facing in that respective week. He knows the playbook and you don't want that to bite you in the butt.
However, after this game, all bets are off. If Brandon Jackson were to struggle and with the Bills game behind Green Bay, Lynch is the type of risk worth taking IMO.
Now, I only bring this up because of Lynch's name apparently being tossed around inside the front office. Personally, I'm a fan of the talent Lynch has. Behind the Packers offensive line, I think he could be really solid. His ego with Finley's ego though might be a lot for Aaron Rodgers to handle in the huddle.
