Whittingham finds/interviews/recommends, Harlan works the contract/money. Generally in that order. All three must agree, to culminate the deal. I expect there is some compromise if their is a difference of opinion/interest. I’m not sure Wittingham or any coach had complete hire/fire decision authority, however the HC, is given great deference. The AD generally give’s guidance on money, term, required qualifications, policy (nepotism, integrity) etc., in advance.
