Note: Jack Harbin was a typewriter repairman from Wickliffe (who Martins Ferry just played on 9/6/13), a Cleveland suburb in Lake County. Harbin developed the system and pitched it to the OHSAA for a number of years using simulated models to show how the system might have worked with that years actual results, had it been in place. They finally decided to give it a try in 1972, and in its original format, there were 3 classes AAA, AA, and A, with 4 regions in each class. Only the region winner made it to the playoffs, which meant that there were only 12 teams that made the playoffs each year for many years, as opposed to the 224 under the current format. that also meant that there were only 2 playoff games per class, a semifinal and a final. I have read that the playoff system which Harbin "dreamed up" completely on his own, is the basis for many other playoff systems across the country.
