While some of those shots are quite nice, we have to realize that the camera is here used in a totally alien manner compared to how it was used seventy years ago. A that time the aim was not "art", but a clear and high quality photograph, plenty of DOF and maybe a fill-in flash thrown in. Just look at the great press photos of the time. If a photographer would have come back form an assignment with photos like this, lens sitting crooked etc, he would have been the laughing stock of the whole profession.
Times change, but these reflect the large format aesthetic of today, as we can not compete against 12 fps high ISO digital SLR cameras with Speed Graphic in the field of pure sports photography, and Mr Burnett is not even trying. At the time when Speed Graphic was the best press camera real press (and sports) photographs were taken with them, let's not forget that. And they did not look anything like these Olympic pictures.
