It depends on where you are, and what mechanics your state or level uses. These mechanics are correct for IAABO officials. Officials in Ohio, Louisiana, and Arizona also switch opposite the table on fouls, as do men's college officials. NB: Tableside mechanics are included later in the video, because IAABO boards in Maryland and Delaware use tableside mechanics.
This is IAABO. The difference between IAABO and men's college is that Lead opposite does not do the long switch in college (moving down the court to lead) after calling a foul where there is a change of direction.
Thanks for the video. It reminds why I DON'T LIKE 3 man officiating ! Excellent instruction. But why to much excess rotations of mechanics. It should be MUCH simplier.
