Preferred Qualifications are just that. Not mandatory. If you are like me, and a tie goes to UND connections, then you put that in there to prevent the coach not selected complaining that the decision wasn't fair.
The "UND Family" is a big deal. The culture draws recruits and keeps former players connected which maintains interest and $ coming in.
Hire a coach who doesn't see the value in maintaining those connections (see Lucia at MN) and you can hurt your program.
UND is a small financial fish in a big financial pond with the Big10 and other big schools putting more into hockey. $ is becoming a huge deal in getting guys from the portal and keeping guys you want to keep. UND cannot afford to lose the benefits of the UND family.
Doesn't have to be a UND guy to keep it going, but you better hire the right guy.
