Unless those that get the latter rounds typically have other 3 person experience that those getting to the first rounds don't have.

Same thing applies (mostly) in Massachusetts. Two-person crews for most high school games all season.

But, for the post-season tournament, all games are three person. College officials are the only ones with significant three-person experience. Most tournament crews have at least one college person, but not all. But, for later round games, all-college crews are much more common. Some will say they are the better officials and should get the late round games, but I know several very good high school only officials who are not able to get late round games because they are inexperienced in the three person mechanics.

Through the years, these officials build up experience...but it is not the same as a regular season of 3-person mechanics.

Game video... no real help.
 

Just posted a couple of days ago. big chunks of the game missing at the end. no real help.

People who work only (or mostly) college games should not swoop in and take the HS tournament games from people who work a bulk of the regular season.

How do you define "mostly"? Just b/c an official works more HS than college shouldn't eliminate him from HS post season assignments.

Devil's in the details, isn't it?

That is why our organization and the state has, in part, a minimum number of HS varsity games required in order to be eligible for post season games. It isn't a difficult number....you can get over it with one game per week. A person could even work more college then HS and still qualify, but they have to give more than just a token number of games to be eligible.
