While OSI – Opponent Strength Index – is 60 percent of New Jersey’s UPR formula to determine playoff qualification, that index gets its data from each team’s Strength Index, how strong a team is considered to be. The SI has nothing to do with wins or losses, but how each team performs based on its own rating relative to its opponent’s rating, and the final score.
Somerville is the highest ranked team in the Big Central, according to the official Week Three Strength index values, updated by Gridiron New Jersey, the website that calculates such values for the NJSIAA. This means the Pioneers are considered – by the formula – the top team in the Big Central Conference.
While Gridiron does not publish the numbers directly, Central Jersey Sports Radio compiled the values for all 339 schools playing football in New Jersey in 2021, and will continue to do so all season long.
The top team overall in the state was St. Peter’s Prep, with an SI of 98.49. The Marauders are followed by Bergen Catholic (96.33), Cedar Creek (94.51), Seton Hall Prep (92.34) and DePaul (91.77).
Rumson-Fair Haven is 6th at 91.14, followed by St. Augustine (89.86), Ramapo (88.47), Holy Spirit (87.89) and Red Bank Catholic (87.69) to round out the Top Ten.
Somerville is right behind at 87.54.
OSI works so that a winning team gets the full value of its opponent calculated into its average. If it beats a team with an SI of 80 and a team with an SI of 60, it’s OSI is 70 (the average of 60 and 80).
Losing teams get half the value of its opponent. A loss to an 80 team is worth 40, for example. A tie garners three-quarters of the SI value (an 80 would be worth a 60).
