I think a lack of players plays a huge role in the current status of the county teams, and I think it obvious that a large number of players and parents make the decision to go to maryville or Alcoa even if they are zoned for the county. Losing just a handful of players can kill a team like heritage or WB. It causes each school to have a lack of depth which reduces the level of competition at practice. Looking at the county schools compared to the city schools, the county schools had about 40 players each dressed out, but maryville on the other hand had close to 100. That's more depth and more competition for playing time, which only makes everyone better.
High school football games are won with the jimmys and joes not the X's and O's. Maryville and Alcoa have world class coaching staffs but they also have the jimmys and joes. The county schools on the other hand dont have the players to compete.
