NFL Draft, The Wonderlic, and Brady

Alright. If you get sick of defending how "smart" Tom and how good he is at reading defenses, etc like I am, here is a great chart of his Wonderlic scores against all other starting quarterbacks in the NFL. (and if you are bored at work and want to waste 10 minutes the practice tests are fun to take to see how you stand up)

I must confess, I don't see much in the way of a discernible pattern in this chart. But still interesting to see. thank you.

Which all goes back to - why do they make draft prospects take the thing in the first place, right?
