Based on what?? Lastnights game? because that wasn't the case even with 3 backups starting.
I'd say you need to watch the game and all of RGIII's passing attempts again.
Their OL is awful and they have a collection of third string RBs. The redskins WR corp is average. Not a good formula for a rookie QB.
And I didn't watch RG3 last night. I'm at the beach house slamming beers and swimming all day. Watching a skins game isn't high on my priority list.
