Why Aranda? Because he had one great season as a head coach. And we all know that a guy who had one great season would be a perfect fit at Nebraska.
But unlike Frost, Aranda would come in with 10 years of Power 5 coaching experience. And he's coached in the Big Ten. And he has a national title at an SEC school.
This includes three years as DC at Wisconsin -- average national finish was 1st in total defense, 2nd in scoring defense. Aranda's Badgers defense was ranked #1 nationally in scoring defense during his final year there (2015).
Unlike Frost, he's a defensive mind first. He's coached in leagues that emphasize defense. And he even emphasizes defense in a league (the Big 12) that doesn't as much as the Big Ten or SEC (where's he's also coached).
FWIW, I think Frost would have had more great seasons had he stayed put at UCF. It just didn't translate to the Big Ten -- high-powered offense and a "bend don't break" type of defense where you hope to outscore your opponent 56-45 to win games. It's the same reason why I hesitate with someone like Jamey Chadwell (Coastal Carolina currently 21st nationally in scoring offense and 58th nationally in scoring defense against non-P5 competition). Those warm weather climate offenses with mediocre defenses -- finesse over physical -- may not be what's best for Nebraska.
