I doubt that Ragone has more trade value than value for his current team.
As a Falcon Fan i know the worth of a good backup, who knows the system and is able to deliver, if he has to. And that could be the case somewhere in the future, cause Banks wont be Backup forever.
Also i'm not sure, if there's a market for Ragone. Miami wanted an alternative to Fiedler and gambled way too high. Green Bay was in need and got Sullivan. cheap. Apart from the Colts, Kansas, Dallas or Baltimore, were aren't alot of teams, who would need another Qb to fill in as Backup after their starter went down. And QB's like Kitna, Holcombe, McMahon, Dilfer, B. johnson, Ramsey are benched and could get traded in emergencies before Ragone.
