Despite not seeing any of these play, I felt that Ahlberg deserved a vote. Averaging 6.73 yards a carry for his career is impressive, and an outlier in the Ohio history book. No one else in Ohio history is even close. Patterson is second at 5.6/carry, then come Hookfin, Brinker, Harden, Blankenship, and McRae, all between 4.87 and 5.18/carry.
Often YPC does indicate running back quality. That said it borders on the miraculous that Tim Curtis made all-MAC and twice topped 1,000 yards. Reason: he played on some dreadfully weak Ohio teams.
