dagies is spot on - it's all about simplicity. When you look at the iconic logos like Cowboys, Red Sox, and even the Vikings, they're all basic. If UND goes with something like Nodaks as the new nickname, it really opens up the options since "Nodak" isn't really anything specific. You could use the outline of the state with a Nodaks wordmark, or you could decide on the outline of an item or animal and just call that a "Nodak", similar to what the Minnesota Wild have done. If UND goes with Rough Riders, the iconic image of Teddy's hat would be an example option of simple.
