There are at least three cases where it is clear that only 11 votes were used. RBY at 133, Diakomihalis at 149, and Kerkvliet at 285. It seems to me that the root cause is most likely laziness.
EDIT 1: If you look across the roster for those three weight classes there is a single coach who is on all three. I'm not saying Zeke Jones is responsible. I am just saying he is the only coach voting on all three. OK, I am saying he is responsible, even if I cannot prove it. So maybe not laziness?
EDIT 2: Trivia Question: At what three weights does ASU have their three highest ranked wrestlers? Do not cheat by reading the first paragraph.
For completeness, Jones is also the voter for 125 where they have their next highest ranked wrestler.
