And it's in this picture that you can see the laces are in a different position than before he hits the ground.
I'm not sure that last picture is actually the laces......just a crappy picture.
Here's a different angle and the laces are clearly above his forearm just as they were when he tucked it prior to hitting.
Personally, when I thought Buck and Aikman said the ball "rolled", I didn't think they meant ONLY that the ball spun but rather than it started behind his forearm as he was diving and then came up and over the top of his forearm after he hit.
Forearm between the ball and the camera
Forearm now behind the ball after being dragged under him.
In this shot, you can see just the tippy-tip of the laces.
I really don't know. When I saw it, I thought it was moving free of his possession for just a split second.
After having looked at it too many times to count I'm really not sure.
I think the supination of the arm as it was dragged under him is what gives the appearance of the ball spinning in spot but at the same time there appears to be a split second at which the laces rotate faster than his arm. His arm rotates about 90 degrees, maybe more, as you can see his thumb on top of the ball in the first picture and when he lands the entire back of his hand ends up touching the ground.
I don't think it's definitive either way. My instinct tells me the ball did turn a little more than it probably should have but the pictures with the laces on top of the forearm tell me that even if it did turn, it wasn't much at all.
I think it's one of those that stays however it's called.
