Unfortunately, if you go team by team in the NFL there isn't a good fit for RGIII. Maybe the Bills, just because Rex Ryan loves the idea of a dual threat quarterback.
Anywhere but the Redskins would be a good start. He isn't 100% innocent in this situation with his diva attitude, sub-par play, and multiple injuries, but it appears that he is being put into a position to fail at this point.
I would like to see what the kid has with a fresh start.
