Agreed. These are professionals, not fans. If they are being successful opportunities will come their way. If Al Golden becomes an NFL DC or a college HC again, that's probably a good thing. He was reportedly approached by UC when Fickell left and said thanks anyway, so that might give us some insight as to where is head is at versus Rees who is 30 and gets offered a job by Saban. Realistically, the OC they are about to hire may likely not be around to see Minchey graduate.
That being said, Andy Ludwig has been at Utah forever and he's 58 years old. If he comes to ND, based on his age and resume, there is a good chance he leans toward staying.
In reality, you never know. Often times, these guys don't go out looking for jobs, the jobs find them.
