I could see Green Bay, Detroit, Baltimore, the Chargers or Jacksonville trying to sign Gilly.
Doug Whaley sucks at the RFA process - he screwed it up with Hogan and he may have just screwed it up with Gilly. It seems to stem from his lack of awareness of how other teams value players, which (not surprisingly) is also the reason he misplays the draft when it comes to QBs (he always seems to think they're going to go a round later than they actually do).
