We might have to agree to disagree on this issue, because I think Perlman's responsibilities went well beyond football. I'll grant that athletics in general could have been one of his top 5 concerns, after things like enrollment, endowment, and research, but I don't think you're ever going to convince me that he should have played anything but an indirect role in hiring and firing coaches, and by that I mean hiring a competent athletic director. I don't think Nebraska football fans appreciate real well that UNL is an academic institution first and foremost. If you want to criticize him for something, criticize him for the university losing its AAU membership on his watch.
Your point about stakes is valid. But if they had this conversation and SP gives him every reassurance he has his man, I don't see how that is Perlman's problem, because, as I am saying, his job is much bigger than making sure SP knows how to do his job.
To make the point another way. If Perlman asks SP, "who you gonna hire to replace Frank?" And SP says: "Dave Wannstedt." And Perlman goes, "who is that, is he any good?" And SP says, "yes, he is currently coaching the Dolphins in the NFL and I have an agreement in principle with him." I think that's a perfectly reasonable exchange, because I don't expect Perlman to know that much about football or have that much of a stake in it.
