It was interesting seeing the speed breakdown on the replay there. Imagine having so much more speed that you're consistently 1-1.5 mph faster than the next closest competitor toward the end of a 400m race...until you shut it down voluntarily because it's only a heat.
I'll admit that I showed up tonight to see if a second Kersee athlete would fall and blow their chance. Imagine the headlines! This place would've melted....
