Let me preface this by saying I am not completely against the idea of bringing Butch back.
However, going back to someone like Chud, Butch, or ****...even if Jimmy Johnson decided to make a comeback...it's not going to signify an instant return to glory. Coker made a mess. Shannon made it worse. Golden made it better, and now it's worse again. No matter who takes over, they're going to have their work cut out for them.
My main gripe with bringing back someone who has been in the program is that we'll all be expecting the Butch/Chud/JJ that we all know and love right off the bat. I'm not sure there are many guys who can turn this thing around overnight and make us a 10-win team next year. Also, I don't know that you can make progress by trying to go back to a well where you've had success before, because quite simply--times have changed.
There's no magic bullet hire. As they said in the movie Idiocracy: ****'s bad right now. It's not as easy as putting water on the crops instead of Brawndo. I think Golden has taken it as far as he can, but this is a reclamation project. The next guy will have to cut out some cancers, and he's going to have to be really good at being the politician that you have to be with the BOT, Prez, and AD (whoever ends up in those positions) in order to get the funding and support to do what they want to do.
