I agree that there is a KSU person on the ground. And I would assume that people would look at him. The rest is all assumption on each of our part. I see McCormack purposefully putting his feet in locations. My assumption is because he didn't want to step on anything while he was yelling at the KSU guy; your assumption is that he is stomping on someone. Neither assumption is definitive.Look at everyone looking down. They are obviously all looking at someone on the ground. And that is in not stepping over someone. It's targeted.
Do you really expect a video of his foot in a guy's chest or something in the middle of that melee?
I am sure we'll hear from all parties over the next 24 hours and we won't have to assume much longer. If a KSU player was stomped on by a KU player that there will be a statement from KSU mentioning it. If they come out and say that it happened then your assumption is correct, if they don't then mine is.
