So maybe I'm missing something but it sure looks like the DIAA division rankings are based on however the conferences place a team. The way I read the fall tournament manual, for the Blue Hen and Henlopen conference, it is based upon which conference they are in. For instance. Let's say the Henlopen decided to put 9 teams in the South, that would be it, they are all D-II. The tournament manual has been reworded a bit from previous editions, which I found interesting. n previous tournament manuals the always had a specific number.
"Item 4. Tournament Field A. The 2018 DIAA Football State Championships will consists of a Division I tournament and a Division II tournament.
1. The Division I tournament field will be comprised of the Blue Hen Flight A Champion, the Henlopen North Champion, and four (4) at-large teams or more if needed to fill the bracket.
2. The Division II tournament field will be comprised of the Blue Hen Flight B Champion, Henlopen South Champion, and six (6) at-large teams or more if needed to fill the bracket.
3. The school classifications can be found in General Item #6. B. Eligible Teams: 1. All teams must meet the criteria established by DIAA Regulation 1006.2.4 to be eligible for Tournament consideration. 2. A team must play a minimum of eight (8) games at the varsity level in order to be considered for the tournament. Forfeits will count toward satisfying this requirement. Only those opponents who have played a minimum of an eight game varsity schedule will be included in a team’s record. Forfeits will count toward satisfying this requirement 24 3. Any school which does not wish to be considered for the tournament must notify the Football Committee Chair by November 10, 2018 so as not to be considered for seeding. Once the committee seeds the tournament, any team that withdraws will be subject to DIAA disciplinary action and that tournament berth will not be filled.
4. For the DIAA state football tournament, the regular season is defined as a school’s first ten (10) regular season varsity football games and they must be completed by Saturday, November 10, 2018. This includes in state and out-of-state school teams.
5. All varsity football schedules will ‘lock down’ on October 1, 2018. No changes can be made to a team’s schedule after this date. If a game is postponed and cannot be made up do to circumstances beyond the control of the member school team, that school may petition the Football Committee for a change in their schedule. No other changes will be accepted and a team’s index will be based on the number of opponents on their schedule as of October 1, 2018. C. Conference Champions: Each conference is responsible for selecting its playoff representative and for making such scheduling adjustments as are necessary so that its champion is available for the playoffs. In the event that a conference champion is not eligible to participate in the tournament or a conference chooses not to send its champion, the committee will use the at-large point index system to choose another team. The conference must notify the Football Committee Chair by November 10, 2018 if their champion will not participate. D. The teams in each division with the highest point indices, as calculated in 2.B, who are not the conference champions will be the at-large representatives.
