ESPN 'returning offense/defense' rankings70th

I’m not sure if we should consider this positive, negative, or mostly irrelevant, but ESPN has rankings of which teams are returning the most of their offense and defense. Nebraska ranks 3rd overall, with 76% of its offense production returning and 78% of its defense production.

It is worth noting that defending NC Michigan is 128th (out of 134) and Ohio State is 70th, while Northwestern is 6th.
