I think Stoops has done a good job of recruiting to Kentucky which is a huge component of being a successful coach. Now that he has established that he can sell the program to HS kids he needs to develop the managerial and development skills necessary to be a successful long term coach.
Going from a position coach to a coordinator is not a huge step, but going from a coordinator to a HC is a huge step. Position coach to coordinator is more of a linear progression, but going from a coordinator to a head coach is a huge step - change goes from linear to exponential. Instead of being in charge of one side of the ball and 45 kids you are now in charge of all 110 plus kids along with all coaches, staff, managers... Also, you are the face of the program to the community, to the AD and University President, booster club, alumni, BOT, media, parents of the players... Anything goes wrong with the program or players you are on the spot. DUI, break curfew, criminal issue they come to you. The Offensive Coordinator sits at home having dinner with the family while you are at the campus police station that night and the AD/Presidents office the next day discussing options for the kid who got in trouble.
Stoops has shown he will make changes and not stick with things that are not working, and next step is to let the guys he hired to run the offense and defense do their jobs. Provide direction on what you want the gameplan to be. It appears that he is wanting to run a balanced offense with a solid running game behind a big oline which would help control the clock, tempo, and not put the defense in bad situation.
