My guesses. I have no idea who the "we" is but I suppose it is meant to say that Husker fans are smart but the coaches arent.
Riley went with people he knew and trusted and thought they could get the job done with a change of scenery. Perhaps he thought more talent would bridge the gap to the past. It is a logical move, I see it all the time in my world of work. Sometime it works sometimes it doesn't. I do agree with the comment that it gave Riley an easier start to work with people he knew and trusted. You have to give Riley credit for making these changes, he is taking the bull by the horns.
Eichorst, very likely, had nothing to do with any of the hiring or firing decisions. After they are made, and he would be in the know, then he gets involved. This is all Riley's call.
If Riley or any coach gives in to the negative people, like those who want Lang's gone, Perella fine, CSV gone and others then it will be a coaching caraseaul.
Everyone could be disappointed if this is not the "splash hire" some are crying for. First, I don't really know what that is. There are only a small number of the top dogs and it would not easy to pry them away and in spite of whatost on here seem to think, money is not the determiming factor.
I for one will sit back and read the bizarre speculations and wait for people to do their jobs in finding the right person(s). Some can wait for a Riley call for your opinion.
