No, Callahan isn't a Husker. He never tried to become one, and that will help doom him.
If he had tried, I'm sure the Husker Nation would have welcomed him with open arms.
The next coach doesn't have to be a Husker, but he needs to embrace what being one is, and become one.
and i think if he would have done that and leveled with the fans about his shortcomings as a HC with a pledge to make some defensive changes, then sure, people here would have gave him more time.
the most disingenuious thing you can do is to insult a Nebraska fan. maybe not the most well schooled or traveled people in the world, but damn straight about being treated with some dignity and a respect for a tradtion that took 25 years to build and perserve!
