Yeah it's my understanding that we needed to get rid of Diaco, and to do so the buyout had to be paid out ASAP. So DB went to the donor(s) and said look guys what do we need to do to get that done. One of the conditions was essentially hire Randy.
If the choice was Diaco v Randy then DB made the right choice, even if it didn't work out. From his perspective I'm sure he thought it couldn't get worse, Randy had a good eye for talent, runs a clean program, and could get us to build back a foundation. All while doing it on the cheap which allowed us to free up money elsewhere (which I'm sure also helped get us out of the AAC). Randy's experience running the program as an Independent in the past probably also helped make that decision easier.
It didn't work out but it made sense at the time. I don't know if all of this is true but these are things I've been told.
