I'm also a Broncos fan and want the coach fired, but it is different than Nebraska for many reasons. First, if an NFL team loses, it improves their draft stock next year. Second, being a fan of a pro sports team is way different than being a fan of a college team where you actually went to school. I gave my blood, sweat, tears, and lots of money to the University of Nebraska. It is much more of an emotional investment as a Husker fan, and there is never any benefit to losing. I would never cheer against Nebraska, and even though I definitely think Frost should be fired, it hurts me to say it and will be sad when it happens but still hope we win.
The Broncos on the other hand? I like them, but it's not personal to me, so f**k it they can keep losing and fire everyone.
