It's FS. Most of the time it results in failure, except for rare cases like Chip, who happened to be head coaching material from the outset. It's like promoting an engineer to be a manager of people. Some can do it, but most can't. Totally different skill sets. Technical prowess and ability to strategize against an offense or a defense rarely translates to a CEO level ability to manage your henchmen, your players, your business, and guide your program to success with an eagle eye's view of the larger picture.
Let me educate you. Oregon fans thought after Chip they would get someone godly. They promoted Helfirch. He proceeded to shit himself, and then Oregon responded by hiring Taggert. Taggert was mediocre losing 3-38 to UW and doing nothing and still left that loser piece of shit party school for a party school that has at least won a championship.
Oregon responded by promoting a coordinator.
Don't you fucking losers get it? Urban, etc doesn't want to come to Eugene because it's a shit hole and Oregon is a piece of shit party school that will never win anything.
Elite coaches don't even respect you. Your D coordinator sure as hell didn't.
