Upperman, Westview and McNairy County are the top three at this point in my opinion. Next group would have Austin East, Loretto, Harpeth, York. Then, not particularly in order, DCA, Milan, Ezell Harding, Gibson County, Elizabethton Claiborne County, Livingston Academy, and Lipscomb. That'll be my top 15.
Several teams not on the radar may make some noise by seasons end. In my part of the woods I know of three teams that no one will want to play in late Feb: Seymour, Loudon and Anderson County. Any of these three could end up in a substate game.
