The SU AD must think that the most important coaching qualification for staying relevant in the NIL age is being a recruiter. If the talent you develop is going to go elsewhere when they can then you need someone who can replace them quickly.
But if money is the main draw for good talent, then a good recruiter isn't going to overcome that disadvantage. Maybe the donors are looking for evidence that we can get talent here before investing. If so, then someone like Brown can make sense even if he sucks at everything else. He can set a precedent if nothing else.
