Until looking it up I didn't realize East TN stretched that far myself. Haven't seen Soddy in a couple years, but I've seen most of the teams listed here and I've seen some of the teams from other areas that Soddy has dominated.
From the teams mentioned here in ET top 10's, they gave good solid spankings to William Blount, Powell, Farragut and Walker Valley. I would pretty much have to agree with the assessment of 3rdbasecoach.
