Adjusting from 2-person to 3-person mechanics (2PO to 3PO)

[ilyazhito]

I found out that not rotating late in the shot clock is an evaluation criterion (as well as a suggestion in the CCA Manual) for NCAAW and NCAAM, so I will not rotate if there are 5 seconds left on the shot clock in any HS shot clock game, unless my commissioner or supervisor says otherwise.

That said, any other things an official transitioning from 2 to 3-person needs to know? We've covered switches (tableside or opposite, depending on state/level), responsibilities of the Center and Lead officials, primary area coverage, and rotations. In 3-person, Trail is not automatically the calling official on last-second shots. It's either the outside official opposite the table (OTO, can be C or T) (NFHS/NCAAM) or Center official (women).

Here are some other things I have noticed about working 3-person games. Other than standing at different places, or having clock responsibilities for the initial jump ball, I haven't noticed much of a difference in pre-game duties or jump ball duties as the U1 or U2. I know that R is supposed to administer the alternating-possession throw-ins for the 2nd, 3rd, or 4th quarters, but the position of the umpires is undetermined (obviously, one becomes Lead opposite the table and the other becomes C tableside to start the appropriate quarter after leaving the blocks to retrieve their respective teams, intermission (except halftime) being just another 60-second timeout in high school). I guess that the umpires go to the block closest to where they were when the quarter ended (In 2-person, both the R and U1 are at the division line opposite the table, in 60-second timeout positions with the ball coming in opposite the table, and the R administering the throw-in), and go from there. For halftime, they would just go to the blocks on the same side as they were when watching warm-ups.

Is there anything else that I am missing?
