Jack, I basically agree with you. That is why, whenever a poster says that Kelly needs to go, i ask who the poster thinks should replace him. As you are aware, most posters dodge the question and say that Swarbrick should have a list of potential candidates. They apparently think that all Jack needs to do is snap his fingers and these candiates will come crawling to ND. That's unrealistic.
We all recognize that Kelly is not without his flaws. That said, I don't see any realistic candidates out there, i.e, I am excluding Saban, Meyer and Stoops, who I think would be an upgrade from Kelly. I think Kill is a very good coach, but I don't know that he is better than Kelly. I don't think Clements has any chance at all.
If there would be an opening, my first choice would be Charlie Strong. I have no idea whether he would leave Texas for ND, although he was an assistant here.
