You're getting unnecessarily defensive. Obviously you're welcome to speak your mind, just like everyone here is welcome to disagree. :dunno
I don't necessarily disagree with your logic about why some winning coaches may not want to come to Nebraska if they're currently having success, but you painted an incredibly broad brush about 'winning coaches' not wanting to come to Nebraska, even calling it a quicksand job. Unless there's some kind of quote or evidence that coaches think this, then that sounds awfully like a projection. Few people, with a straight face, are looking at Frost or Riley and thinking they got a short end of the stick. Chances are that a number of winning coaches would jump at the opportunity to coach at a university like Nebraska, particularly some P5 ones if the money is right.
Yeah, the recent W/L record at NU sucks, but you dangle a high enough salary, pretty good recruiting capabilities/resources, the brand new facilities, the fan base, and some job security in the contract, I stand by what I said - there will be a good coach willing to jump into that quicksand. The college football world is a wild one.
So, we'll see how it shakes out. If Nebraska ends up targeting a number of successful winning P5 coaches and strikes out on every single one then I will come back here and eat crow.
