I realize that this is the rule, or at least as it was conveyed to me a few years back. I understand trying to fill an 8-man brackets at Districts, I just don't understand why they wouldn't want to fill all sixteen slots for State (a little more revenue for whoever the revenue at State goes to). This is the only thing that I can think as to why this is the rule: D1 places four, D2 places 4, D3 places 3 and D4 places 4 (15 of 16 spots filled). D1, D2 and D4 all had at least five wrestlers and it would be a logistical nightmare to figure out which 5th place finish gets to move on (without a coin flip, or maybe rock, paper, scissors).
