Using Clanton as the geographic center of the state, there are many more 3A teams NORTH of Clanton than there are SOUTH of Clanton.
Also, if you draw a line from east to west across the middle of Jefferson County, the two regions which include Cordova (region 4) and Clay Co (region 5) have half of their teams NORTH of that line, and half SOUTH of that line.
So the finalists could just have easily (from a geographic perspective) been Greensboro (region 4) vs Hokes Bluff (region 5). That wouldn't have been as confusing.
Here's a link to the current 3A Region map:
