Exclusive: Here’s a look at unofficial updated Strength Index numbers for all NJ Football teams following Week One play

With the shutdown of Gridiron New Jersey over the summer – and the job of calculating the NJSIAA’s complication playoff formula moving to NJ.com, Central Jersey Sports Radio will continue to run its own unofficial numbers all year, and that includes the Strength Index calculations, which are critical to figuring out a team’s OSI (Opponent Strength Index), which is 60 percent of the playoff formula.

NJ.com is expected to debut it’s playoff standings after Week 2 action this weekend, just like Gridiron New Jersey did, but it’s unclear whether it will be publishing the Strength Index numbers on a weekly basis, something Gridiron did not do. However, Gridiron would update each team’s page with their current SI value. We would run our own numbers to compare with Gridiron the first few weeks, but no such mechanism currently exists.

So, we’ve run our own calculations once again this week, and are publishing today the unofficial updated Strength Index values after Week one of play.

Each week, SI values change based on the final score and the rating of the two teams that played. Here’s an example. SI goes up or down depending on how a team did compared to the difference between the two teams. If Team A (80 SI) plays Team B (60 SI) and Team A wins by 20, there’s no change. If Team A wins by 10, they underperformed by 10 points, and Team B overperformed by 10 points. Team B increases by 2 points to become a 62, and Team A drops to a 78. Team A then gets the full value of Team B for its OSI (62) while Team B gets half the value of Team A (39).
