Seems football-related to me. The twins have been discussed on here before ... most of those discussions turn into arguments of the "they're not so hot ... they're just attention hounds" versus "they're attractive girls ... they present good publicity for Bama" variety.
Best I've been able to tell from reading the threads is that they are nice, friendly young ladies ... and I like that they seem to dress in a classy, non-slutty way.
They may not represent the absolute "hottest" section of the Bama female population ... but they present a wholesome, attractive image for the school in my book.
