Please, If we have to get a new coach can we get one who has been one before.
I don't get this. Why are we so willing to take the chance on a coordinator who has zero head coaching experience?
Because there is zero evidence that a hire with head coaching experience is better than a hire without.
If you look at the current BCS Top 25, about exactly half of those coaches are first time head coaches.
Oregon
Stanford
Baylor
Clemson
Oklahoma
Texas A&M
Texas Tech
Just a few examples. For every coordinator turned head coach that failed you point out, I can point out another head coaching hire that was a head coach before and failed. Hell, this should be easy as pie to understand for Nebraska fans. Tom Osborne was never a head coach, but Bill Callahan was.
(p.s. please don't strawman me responding that I'm trying to prove a point by cherrypicking certain instances. I'm not. I'm only countering false points.)
