As a loose rule:
beginning at the Canadian border, females gradually get hotter as you progress further and further southwards towards the I-70/Mason-Dixon Line.* Below the Mason-Dixon Line, all bets are off, and debate over comparative hotness may begin.**
Unfortunately, only one Final Four school lies below the Mason-Dixon Line. Therefore, University of North Carolina automatically has the hottest girls in the Final Four. Debating the issue is a futile waste of time.
*NYMetro Area, Chicagoland, and Madison, WI are exceptions to the loose rule.
**Note that both Overland Park, KS and Prairie Village, KS are below I-70.
