1A and 2A were put into districts together for the regular season based on proximity to each other. Then there was Voodoo math to determine the pairing to figure out where everyone went during the 1a and 2a playoffs. For a couple of years SP was in a district with 2A Marion County and Signal Mtn (who was actually a 4A team that got under the numbers during classification. During the playoffs during that stretch SP actually played Fayetteville and Columbia Academy in the playoffs. In fact, Greenback played CA a couple of times in the playoffs. It ran for 6 seasons from 2009 to 2014. In 2009 & 2010, South Pittsburg, Whitwell, Lookout Valley, Signal Mtn and Jasper were in the same district.
