In 2018, the NJSIAA made its biggest overhaul of the playoff formula since the advent of power points in 1975, the second year of the playoff era. The “NJ UPR” system kept traditional power points, but added a new metric called the Born Power Index, which ranted teams based on scores relative to each team’s rankings.
Though it was only used for one season, the NJSIAA made its own variant called Strength Index in 2019 and flipped it around, using the Opponent Strength Index as its additional metric, which it still does today.
But the Born Power Index continued online, as it had for many years, a system invented nearly 60 years ago. Bill Born, the formula’s creator, did rankings for New Jersey and Pennsylvania high school basketball and football, as well as college football

One Big Central Conference coach mentioned to CJSR this weekend that he noticed the site hadn’t been updated this year. As it turns out, William Born passed away at the age of 83 back on April 6th of this year.
According to his obituary, which can be found online, William E. Born was born in McKeesport, PA, on October 1, 1941, grew up in Scotch Plains, and moved to Berkeley Heights in 1973. A William Paterson alum, he played basketball and baseball there, even playing minor league baseball before beginning a long career as a math teacher, where – always obsessed with numbers – he developed the Born Power Index.
In a 2018 interview with Mike Pavlichko on WCTC’s now-defunct “Football USA” program, Born said his father once told him he could reasonably project the outcome of games by using simple math, including scores, and how teams fared against each other.
Born said he had been asked by an area basketball league to assist in seeding their tournament, and his rankings were used as a guide. Several newspapers printed his rankings on a weekly basis.
Though the NJSIAA developed a similar formula of its own, the change was prompted by an outcry when it was found that, the way the rankings were used, teams could increase their chances of getting higher seeds by beating teams by more points.
But the system itself was not the issue; in fact, it may even be more accurate than the current OSI formula. It was the implementation that didn’t work. Had the NJSIAA turned it around and used the Born Power Index value of a team’s opponents, rather then a team’s own value, we might still be using it in 2025.
Born had said the “genius” for the formula was that it took all kinds of factors into account, including weather, injuries and field conditions. While there was no numerical value assigned to any of those factors, he believed all of those things factored into the score.
If a star player was hurt, that might be reflected in the score. If rain kept a team from passing and kept a team from scoring, that would be reflected. A team that has speed might play slower on natural grass than turf, again affecting the score.
