How Absurd Is A 40 Yard Dash Time?

Aaron Ross stands out as a physicl specimen. Speed is good, the 3 cone is better because it shows that stop start and side to side ability which is just as, if not more important in a CB. We all remember Michael Hawthorne right. Dude could not turn his hips and go if is life depended on it. Yes he had great inline speed, but didn't have that lateral and body turn movement.
If a CB was a tad slower, but got up to speed quickly and could twist and move on his hips I don't think the lack of speed would hurt so much.
Remember also, play reaction speed is just as important. That is where Sammy Knight always excelled. He knew what the WR was going to do seemingly before he did it. Some guys have that knack, and it can make up for lack of speed also.
