They have to be obsessed with the rankings because they need the outside validation to tell them that Sumrall is the guy. Just like they needed it to tell them that Billy was the guy, and Mullen, and McElwain, and Muschamp too. They don't even know what a good team looks like anymore because they've been gaslit for so long into thinking they had a good team each year.
They're just an insecure, desperate chick with zero sense of self and acts like they're all that, but in reality will go home with the first guy that hits on her at the bar.
