What Role, If Any, Would You Be OK With Bringing In Jimmy G?

Jeremy Fowler brought up the potential signing of Jimmy G. In what role would you be ok with bringing in Jimmy? Mentor? Backup? Stop Gap to not draft QB this season? More? None? I find this interesting because I also wonder what the market will be for him and what the guys in the front office and on the coaching staff think of him. IF they don't like these quarterbacks I guess you could do worse, but the only thing is he cannot stay healthy so maybe we would have to be prepared to see Davis Mills or whatever other QB is on the roster at some point.
