Wanted to go ahead and put this out there. In AAA I can name 4 teams that should be back at the top next year:
Upperman, Greeneville (how many seniors that get playing time do they have?), Jackson North Side, and Heritage (I don't believe they lose anyone of real importance). I know these 4 teams return their best players.
One new team to watch for is Alcoa, as they will be in AAA this next season.
Fayette Ware loses their 2 best players.
Tullahoma loses their stud in Farrell and arguably their 2nd best player in Johnson, but I believe keeps the rest of that supporting cast.
I believe South Side is mixed pretty well between classes, however, they lose their big man in Chris Mitchell and one of their best in Liggens, but I believe they will still be competitive next season. Regardless, I expect North Side to win that district this next season.
Hume-Fogg loses 6 of their top 8 players (Keep a really good Junior and a Sophomore), however I have heard from numerous people that their best player, Nwoye, from this past season has a 3rd brother who will be a freshman next year and many say he is the best one of the 3 brothers. Time will tell. I expect Hume-Fogg to compete in the postseason again, but we will see if they have enough to make it back to Murfreesboro.
I expect Fulton to continue getting better, as I believe they are pretty young still.
This is just an early list. Let us know who else should be considered and why. Any information from out East and West is especially appreciated.
