As history has proven, anything can happen during the course of a season. But assuming all the teams are able to maintain their roster and not lose any key players to injury or other reasons, then my current thoughts are:
I think Middleton is clearly the favorite and should be able to control their on destiny. However, I believe that are 2 or 3 teams that could sneak up on Middleton if Middleton does not maintain their focus and forgets to bring their "A" game.
I think Riverside and Scotts Hill may fight it out for 2nd and 3rd. Riverside only lost 1 starter from the good team they had last year. Scotts Hill lost 4 starters from last year's team but I think they will have a good young team that could prove to very competitive once they get some game experience under their belts.
I think TCA should fall in about 4th but could prove to be a real challenger for the 2nd or 3rd position as they have some good key players returning from last year's team.
I think Madison may come in about 5th depending on the play they get from Smith and Murphy and the supporting cast.
I think JCS and Adamsville may duke it out for the 6 and 7 position. JCS lost 5 or 6 seniors from last year's team and Adamsville will need to prove that they can compete this year but could prove to be a spoiler for a few teams.
As always, I think there's going to be some good basketball games to see in district 15A this year. Good luck to all the teams. Stay healthy, play hard and play with good sportsmanship.
