If you still think that a racial slur was used, why did Smart apologize to Orr,then? No ifs ands or buts about it.
First of all, I'm not saying a racial slur was used or not, but I could see why he would apologize for it:
1) Because he represents Oklahoma State University and his use of physical violence was inexcusable
2) Because if he swallows his pride and apologizes publicly, the media can stop making such a big deal about something that wasn't really that big of a deal.
3) It shows NBA organizations who are looking at drafting Smart that they shouldn't question his character and the incident was a fluke.
I've worked in corporate types of environments long enough to know that when something bad happens, you move on with it and you listen to what your superiors tell you to do for damage control. The more you fight it, the worse off it ends up for everybody.
