Robert Griffin III is pretty good at this whole quarterbacking thing. Sure, you know what he's capable of doing with the ball in his hands. He's got the arm and accuracy and his legs leave defenses guessing. It all has to start behind the line with those little things, like this play fake.
RGIII reads the defense, and fakes the handoff. He's doesn't just fake the handoff with a half-assed arm gesture like a lot of quarterbacks would do, he goes all Meryl Streep with it.
