Depending on where the byes end up someone could wrestle more than 5. This can happen if there are two adjacent sets of matches in the first round on the same side.
12 team regionals make sense. They can be wrestled in one day without jeopardy of breaking he 5 match rule.
Hopefully the 40 40 ?? reclass with 10 schools in each regional, wrestling in an 8 bracket format would eliminate almost all first round byes. Hopefully 10 schools can fill an 8 man bracket in each weight class. But, I do think you will continue to have some first round byes, but a lot less than now. An over filled weight bracket with 9 or 10 wrestlers will require one or two pigtails/wrestle-ins. Pigtails should be one and done matches: the loser would be eliminated to preclude an odd ball one team losers bracket. All other matches proceed through a normal 8 man bracket front and back side--after all you are looking for the 4 weight class placers to go to the state tournament .
An 8 man bracket with 10 wrestlers would require a 10 VS 7 and an 8 VS 9 pigtail/wrestle-in matches. An 8 man bracket with 9 wrestler will require only an 8 VS 9 pigtail. To preclude a 1 team odd ball first round losers bracket, the pigtail would have to be an elimination. Maybe harsh but needed for 1 day regionals. After the pigtail round and the slotting of the winners it becomes just a true 8 man bracket.
I don't see any PRO or CON replies from 654A coaches. In fact I don't see any comments at all. Discussion points from 321A folks would be welcome. Is everybody neutral or just don't care--sorry to say but very typical in this forum--sad in either case!
