For a rookie QB, isn't the eye test - has a strong arm and throws a nice spiral? If he does that and has pocket presence and looks comfortable he usually isn't a rookie in his first start.
I disagree. There a million guys who have a strong arm and throw a nice spiral. They are not all NFL QB's. There is a certain look to an NFL QB, the way they drop back, the way they survey the field, the way they deliver the ball, the way they act, I did not see that from Geno. I could be dead wrong, and hope I am, but that is just what I observed.
