I think the people that say they can't see anything, or are unsure of what they see are just trying to convince themselves. What I see (and it is obvious), is that he not only extends his foot but he turns it so that he could sweep the refs heel. Every kid knows how to do this. you hit the heel as it comes off the floor and the foot gets caught behind the other foot. Most people don't fall but rather stumble. If this isn't addressed, sooner or later he will do something that will embarrass the University and/or himself in a much more public way...
I'm not pleased that he is the face of the basketball program this year..
