I think #1 and #4 are questions that are answerable questions.
On #2, there is ZERO chance, if I am in Dr Maggard's shoes that I would answer this question. This is extremely competitive-advantage information you are making public. if the number isn't great, your rival schools can use it against you, if the number is great, it provides rivals a number to go use to raise upon and motivate their donor base. Are there peers out there that you can cite that disclose the money their NIL collective has?
On the Des question, what is the value of this question on a hypothetical? If he answers yes, and Chandler plus Ben get hurt in Week 1 and the team wins 5 games with an unproven QB, should he get fired?
Or he answers no, and the teams stays healthy and wins 5 games, should he be retained?
Dr Maggard is the boss for all his head coaches. Every good boss I have had, and my job as a boss, is to publicly back employees and privately scold.
I can almost guarantee you his answer to #3 is that his requirements for a head coach have not changed. He wants to compete for conference championships, recruit well, connect to the student-athletes, etc.
