FOX Sports' Jay Glazer says "it's a done deal". It makes perfect sense to me and I think he would be a good fit. The 'Skins need some positive leadership (and a decent QB) and RGIII can deliver. Just look at what Andy Dalton has accomplished in his first year at Cinci.
Personally I think Andy is a better QB than RGIII, but the 'Skins are a better organization in a much larger market. Look for RGIII to light up the NFC East the first 6 weeks before teams adjust their defenses.
