As someone who has seen them all but doesn't have a dog in the hunt, I'd have to give a slight edge to Coffee County based on experience. Two talented, veteran pitchers and a large group of seniors (I think 7 on the field usually) who made it to the substate last year make this a team to be reckoned with at tournament time.
Lincoln County has more than proven they can play with Coffee County. After all, they've beaten them twice already. If there is a chink in the armor for this very talented team, it is youth. Loaded with talented freshmen and sophomores. If they don't get tournament-itis but play the way they've played all season, they obviously are a threat to win it.
Lawrence County has a veteran pitcher with the best off-speed stuff in the district. They are good. My only question about them is, do they know how good they are? There's a process a team goes through when it rises from near the bottom of the pack to near the top. What gets them finally over the top is belief that they can do it. If they believe, then I believe, too, and they are a legitimate threat to win it.
I think there's an obvious divide between those three teams and the remainder of the district. While the rest have some strong points, there is a lot of youth in some key positions, and the pitching might not be quite at the level of the top three teams. They all have some young, up-and-coming pitchers, however, who could make the district a real horse race next year (behind Lincoln County, that is).
