bktballref,
that was a pretty good explanation of mechanics, cant be the first time youve seen them?
in addition
for fouls in the front court the calling official always goes to trail, whether it is table side or opposite. the other two officials switch positions(cannot remain in the same position on a foul call unless already trail).
for fouls in the backcourt the refs just slide(no switches).
also they are taghut to report the nature of the foul.(ie-hit to the head, trip, hit on the arm, etc)
the reasoning for the switches they use is it is a natural movement to just walk to the spot you are going to and report at the same time. also they like for the officials to go trail table side on shooting fouls so they can explain what they saw without long distance communication.
the earliest nba 3-man mech would put the crew cheif(wiley veteran) nearer the coaches because it was believed they could explain/difuse the coaches better than the rooks. ed rush decided about 4-5 yrs that the younger officials were good enough officials to rotate near the coaches and explain what they saw. and so the present nba rotations were born.
