In Conference 18, the two conference tournament finalists represent the conference in regional play. There is no automatic bid. Silly, when one considers that they actually play each other twice, and other conferences do not. But so is the way of this insanely flawed new system.
As of this writing it seems that NR, KF, and Denbigh will battle for the top 3 seeds. NR plays both this week, so nothing will be settled until the last game is played. Otherwise, Lakeland should end up being the 4, and Heritage and Phoebus should wind up the 5 and 6, respectively.
Regarding the 4A South Region tournament; an early peek says that 4 of the top 5 teams in 4A will be playing on the South side of things, assuming they make it to Regionals. Hence, two of them will not make it to the "State Tournament". In no particular order, they would be Glen Allen, Hanover, Nansemond River, and Jamestown. I really don't like a "State Tournament" that only has four representatives. Then again, that's only one of the many things I don't like about "The Great Realignment".
Again, this assumes that the aforementioned do what is necessary to get to the Regional Tournament to begin with. Not sure which conferences apply automatic bids for regular season champs and which ones require the tournament to decided its representatives.
