The results of Week 7 certainly had a huge effect on the seeds in various classes.

What it did not really do was alter the participants in the field as just six new teams found their way into the draw.

Outside of a few upsets such as Glenbard North’s win over Geneva most of the field changes were because of the most difficult element to predict in this whole exercise.

The Chicago Public League is responsible for half of the new entrants largely because it is the hardest group of teams to analyze because of a few of the variables that are unique to the league.

24 of the teams in the Chicago Public League don’t currently have a Week 9 opponent and an exercise that takes into account all upcoming games, that unknown variable wreaks havoc week to week on trying to put together this projection.

In addition, all of those 24 teams aren’t necessarily eligible to make the playoffs even if they meet all of the other standards that all other playoff qualifiers abide to.

Those four divisions (North Central, South Central, Southwest, West) send division winners into the playoffs. They also hold playoff games between the runner-up teams in each of those divisions in Week 9. Those matchups aren’t disclosed until after the conclusion of Week 8 games and there’s no methodology available to try to figure out how the teams will be paired beforehand.

And considering that those teams can come from anywhere on the enrollment landscape those unknown games suddenly become very interesting to the teams on classification bubble lines.

There’s also the interesting wrinkle in this process that declares that even if teams from those divisions have records worthy of placement in the playoff field, they won’t be going to the postseason unless they either win one of those divisions or win a runner-up playoff game, they won’t be playoff eligible.

Using this practice its easy to see how five to seven teams won’t make the field despite having five or more wins, which right now is exactly within the range of teams expected to make the field with four victories.

Speaking of that, this week’s projection includes eight four-win teams, most of which are found in the larger classifications.
