You need to be more specific. Total yardage in a single game? Total yardage in a season? Total yardage in a college career? And is it rushing yardage, passing yardage, kickoff yardage, puntyardage, kickoff-return yardage, punt-return yardage, total return yardage, or total yardage. If it's passing yardage, do you mean as a receiver or as a passer?
Of course, I don't know the answer either way, and really, who cares? It's Division II. It could be a million yards, but whoever holds the record can't hold a candle to the average division I-A player. If they could, they would have played in Division I-A, or at least I-B.
But if you want anyone to answer this question, you're going to have to be more precise in how you ask it.
