I agree with some of what the OP said.
This is why Griffin is so special, and why I like him more than any QB in this league. He has the athleticism and arm to destroy you both ways. There is not another QB in this league that can rip off an 80 TD run AND throw that type of ball to Santana in that past Eagles game.
I feel like it should be ideal for a QB to have decent mobility, especially with today's freakish athletes that we see on the defensive lines today. With maybe the exception of Rodgers, I don't see how any other QB in the league would have had as much success with the Redskins this year.
