I have reserved judgment on Griffin for a long time, but I have to believe Redskins fans are starting to get pretty nervous. Griffin has shown time and again that he has a lot of trouble reading defenses. There were several situations (not just the interceptions) where he had receievers open downfield and he just missed them, either with bad throws or just not making the correct throw. He has proven to be nothing more than a checkdown/screenpass quarterback who is capable of making big runs on occasion.
I'm not saying the kid can't be a good quarterback, but I think he has the longest way to go of any young QB in the game right now.
Him and Kaepernick
Nonetheless, good points.
And yes, many Redskin fans don't think he's an NFL level pocket QB, and feel Kyle Shanahan needs to scheme better for him and the Wide Receivers in order to be successful.
You just have to not go for the fakes, assume a pass (or play your regular defense), and keep a spy on Griffin. He can't throw well or consistently from the pocket. Neither can Kaep. They both need their Pistol, Fakes, Run games and schemes immensely.
