Coaches are naturally going to try and bring in their buddies due to the networking involved in the space. This situation is a bit unique as Kerwin has been a HC at his last 2 stops and brought some assistants with him during the transition. A typical coordinator promotion might include a GA or single position coach coming along, but with him as a HC, he has an entire staff underneath him. The fact that some of his asstants moved from JU to Valdosta with him indicates they might be along for the ride.
By all accounts, he’s loyal to his guys (especially Kade) and I imagine he’s fighting tooth and nail for them to be included on his staff.
