I believe that we would win in court, but I'm skeptical that it will ever get there. I think the NCAA has too much to lose and won't want to see it get there and therefore will try to settle. They don't have a solid foundation for their edict and they don't want their dirty laundry aired in court.
My reason for breaking hockey out in this negotiation exercise is the cost of changing all of the logos throughout the Ralph and the powers that be won't allow hockey to change during a negotiation. The football team already has the interlocking ND on the helmet and just a small logo on the front of the jersey. I'm not advocating that football make the change, this is purely a speculative "what could you stomach" exercise. Additionally, I don't look down at the other sports as second-class sports. You can probably tell by my past posts, that I'm not a "hockey only" person. I have an interest in just about all things UND.
My vote is that UND wins in court and we keep the Sioux name and logo.
