I can't speak for West and East TN. Region 3 and Region 4 in the middle will have 2 teams a piece, maybe 3 from Region 4, competing to play the beast of the east. In Region 3, LA is sitting at 5-2 with an opponent overall record of 19-28. They have beaten one team with a winning record in 3A Upperman. Dekalb County is sitting at 4-3 with an opponent overall record of 26-23. They have beaten one team with a winning record and that was LA. In Region 4, Marshall County is sitting at 6-1 with an opponent overall record of 26-15. Their only loss was to Tullahoma. MC beat Springfield out of the West handedly. Tullahoma is sitting at 7-0 with an opponent overall record of 24-16. Tullahoma beat 4th ranked MC earlier in the year convincingly. All of these teams will continue to improve, but I see a rematch of Tullahoma and MC in the quarters to see who plays whoever comes out of the East. The East has to travel this year, so it could be an interesting playoffs. Right know it is Elizabethton until someone proves them wrong.
Last year is last year, but I know for a fact Tullahoma overlooked Dekalb County and they were without their starting WR/DB and Dekalb picked on the new starter the whole game. Hence the 4 TD's for Nokes. This is not the same Tullahoma team from last year. Tullahoma returned everyone that contributed last year, except the QB. The QB this year is more mobile which gives another dimension. MC toward the end of last year was not the same team during the middle of the season for some reason.
