Taking from the lists, and noting the leader at every 100 carry benchmark:
1000+ Dayne, WIS (5.8)
900+ Griffin, OSU (6.0)
800+ Williams, TEX (6.3)
700+ L.James ORE (6.6)
600+ Gordon WIS (7.8)
500+ Gordon WIS (7.8)
400+ Love STAN ties Gordon, but Gordon has more carries. We'll see what he does this coming season.
300+ Weatherspoon (HOU) 8.2
*Gordon is the only repeat name on the list, and with only one guy tying him, no one surpasses his YPC for 300 carries, which is nuts.
*Also of note, look at how the YPC increases when you go down 100 carries - 0.2, 0.3, 0.3, 1.2, 0.4. Gordon's increase is 4x the average of the other benchmarks. There is a very good statistical case for Gordon as the best ever.
