At least Bubba Schweigert was younger than Dane Jackson when he was hired to be the head coach.
Both got the positions because of the UND connection,
Over younger, rising stars (chippahs) with more hunger and drive.
Dane, like Berry, now has to learn to run the entire program. As both had never really been a head coach of anything before (unless you count Dane replacing the one coach who died during the season).
Hakstol and Blais, had head coaching experience and were "young"...not hard to see a clear pattern of key ingredients that separate these two groups:
Berry, Dane
Hakstol, Blais
