itzme,
agreed, BA should be favored to take the middle region, if not the state championship.
As far as the east region, I know that both Knox. Webb and GPS were the best teams last year and I would expect both to be tops again this year.
The west region you would have to assume Briarcrest would be in the mix based on their tradition. I know that they are under new direction this year, but always seem to have very ahtletic players. ECS, St. Agnes, and Hutchinson are also fine programs.
