Yeah I'll have to respectfully disagree with this one, at least in regards to 6A. Bearden, BC, Oakland, Riverdale, Brentwood as well as 8-6A. As the state continues to grow, the larger classes are going to show plenty of balance. It's going to get really hard (er) to string multiple titles in a row, especially in 6A.
I could see why you'd think that way if your only exposure to HSFB statewide is the BCB, but Tennessee is in good hands
