I have to strongly disagree with this. Chat Prep is a cheat code in A , but doubt they would have won a game in the AAAA bracket. They lost to a down cleveland team, and beech this year. They do have a decent AAAA win over Walker Valley.
Alcoa was not as good as the AAAA final four. They split with Maryville this year (W by 1 and L by 26) , also lost to Bearden and Morristown East.
Fulton I could see having an argument. Beat Morristown East by 3, Maryville by 9, Bearden by 6. They would have belonged. I don't think they would have beaten Independence. Think they would have been a great game with Cookeville.
I know you can't simply look at common opponents. Basketball is a game of matchups. But I don't think you can really think that Independence was the worst of the 4 champions this year if you are honest about it.
