Some others in northeast Tennessee were:
Fall Branch Cardinals - combined with Boones Creek Bars (Daniel boone's spelling of Bears) and Sulphur Springs to form Daniel Boone
Blountville Tigers - combined with Holston to form Sullivan Central.
Mary Hughes, Bluff City and Holston Valley combined to form Sullivan East.
Lynn View Lynxes and Ketron Wildcats combined to make Sullivan North.
Church Hill Panthers and Surgoinsville Eagles combined to form Volunteer.
Rogersville Warriors and Bulls Gap combined to form Cherokee
Sullivan (referred to as Sullivan West) Pirates was combined with part of the Sullivan Central district to form Sullivan South.
Jonesboro was combined with, I believe, Lamar and maybe one or two others to form David Crockett.
Erwin Blue Devils now Unicoi County - may have been consolidated with another school.
Not all of the schools mentioned played football. I could not be sure about some of them so I did not attempt to name the ones that did and the ones that did not.
