There's nothing to support this. In fact, borderline ridiculous to think it's an improvement to hire a DC with no experience in the south to take over the Bama defense. Recruiting would take a huge hit.
In fact, I'd dare say, you'd be calling for his head in year two because he's proven he can't maintain a defense. Good one year, decent the next.
There are three teams in the Big 10 that are notable. Penn State who they lost to last year. Michigan who they lost to last year. They lost to IU and Iowa two years ago. And that's who you think is an improvement? Ohio State beat 'em twice in 2019 along with a loss to Illinois?
TDS found in political circles is kin to GDS, and you have it in spades.
