Well if Wick, Amos, Hillger, Hamiti and Weiler are all not on the roster next year, I would assume the coaching staff is not either.
Transfers happen, or wrestlers decide to do something else, so it wouldn't surprise me if 1 or 2 ended up not wrestling next year, but making a roster with none of them seems like a waste of time. If they are all gone, it would essentially be starting over from scratch and Bono's first 3 years were a waste.
