Clearly, the SAA photographer hit here, and I missed. If I recall, I wasn't quite ready for the moment, and the center focus point that I had selected grabbed on the pants of the other photographer and not the football player, Mark.

SAA Photog:

This time, my positioning paid off (I got a face shot), and in the 1/10th of a second or so that my camera's autofocus had in between my 6 frames-per-second shooting, it grabbed onto the player for this one shot. In my mind, it could only be better if I hadn't been panning so fast and could have captured Mark's right foot. Then again, William Fandrich (the player in the brown shirt) would likely have blocked Mark's foot anyway. Oh, and if the football was balanced right on the tip of Mark's fingers as he stretched to reach it....
