Judging by current Semi-State Rankings of top 6 teams and top 15 individuals, it looks as if around 15 teams have a decent shot at fielding a full State Meet roster.
3 teams who finished in the top 12 for the NP/FR combined week of scoring currently do not have 5 guys on their teams who are expected to make the State Meet.
Only 6 out of the 12 teams who scored in the bottom half have the required 5 to qualify for State.
Note: This is all on speculation and will be expected to change as the weeks pass and as rankings for each Semi-State vary from week to week.
However, if you feel you are one of the teams who does not have 5 guys who will make the State Meet, I would look at making a trade or adding runners to your team to give you the required 5. A 15 team competition at State would not be as interesting and exciting as say a 20 team competition.
