My first call would be to Frank Vogel.
Known as an X & O guy who has a reputation as a great teacher of the game. Assistants have stated that he encouraged their input and had good relationships with players. Has overachieved with less talented teams and led a talented team to the championship. These are observations from people that have worked with him in the NBA. Pitino stated that he had a great basketball mind and put in the work needed. Believe he is worth a 5 minute phone call.
My other out of the box candidates would be Bob Richey at Furman, Matt Langal at Colgate, and Grant McCasland at Texas Tech. However, any potential candidate would have to answer the following except #5.
1. Why do you want this job and what makes you think you are qualified to be the head coach at UK?
2. What is your recruiting philosophy? Is there anything you want to hear/see from a high school or portal recruit before you offer him a scholarship?
3. What traits do you look for in assistant coaches wanting to work under you?
4. The pressure of this job is enormous with the several million coaches, I mean fans, that are hanging on your every word as the coach. How would you prepare yourself for this challenge 365 days a year?
5. You only have NBA experience. How does this help you at UK? What are some of the challenges in moving to a college head coaching job?
