Gonna need different tea leaves. I think, and it's mostly a guess, people need to start to wrap their heads around Williams as DC. It seems like Brown would be the type of new age thinker who would be willing to give a promotion somewhat similar to the risk SU just took on him.
To be clear, I am not equating the two positions. I also agree that a first time HC is best served by coordinators with experience. Just throwing it out there that I wouldn't be surprised by Williams as DC given what we know about Brown.
