I had a public school AD tell me a couple of weeks ago he's going to push for 3-person crews. NYC only does 3-person in the regular season for AA Varsity in Catholic and Private schools, not public (AA is the highest level of ball in NYC/NYS) and his school is AA public. He said he can't see how we call that level of ball with only two people.
My BV assigner suggested to us a few years ago that we should go 3-person in exchange for a cut in pay to help schools deal with the cost. We're at $105 for 2-person. He said we should go $75 for 3-person, meaning it would only cost the schools $15 for the third, the fees would eventually go back up and more people would get Varsity work. Overwhelming majority of officials said no way. I thought - and still think - the folks who said no were nuts.
NYC publics go 3-person starting with the city QF at all levels (AA, A & B). A few years ago NYS actually went back to 2-person crews for the state semis and finals. The organizers said they were having trouble finding enough officials who understood how to work 3-person so they went back to two. It's back to three again.
