I am not defending Barnhart, he's made a lot of mistakes. But does the OP know that:
- Duke hired a new head coach (Scheyer) who had ZERO head coaching experience, not 1 single win
- UNC hired a new head coach (H.Davis) who had ZERO head coaching experience, not 1 single win
- UL hired a new head coach (Kelsey) who had 0 NCAA-T wins (0-5)
Whenever you try to "hire within The Family" you are restricting yourself from the talent pool, hoping that the additional aspects of that pre-existing bond between the school/fanbase and new hire will make up for any other areas of lack of experience.
Pope had success, relative to where he was coaching (Utah St & BYU before BYU decided to spend big NIL).
