Not that I've been around the state tournament that long, but long enough to see many ranked teams one and done. With the rankings being such a joke (because HS baseball recieves so little attention and dissection), I'd have to agree with FB that the state champion is probably seeded a bit lower than 2 in their sectionals. It all comes down to the string, and how good your #1 and #2 can control the game, not the body of work of the team.
Oh, btw, did I mention that my pick Lake Zurich, is a #3 seed?
