Greg,

Two years ago I posed this question to someone who should have known the answer (I can't remember who, but they were in a position to know). The answer I was given is that they only take four wrestlers from each District to wrestle at State, and if there were vacancies from Districts with less than four wrestlers, those slots would become byes. At that time they were allowing wrestlers from Subs that were heavy to fill in Subs that were light to wrestle at Districts, just not at State.
