NFHS Mechanics Question (3)

[Da Official]

I'm looking over the NFHS Basketball Officials Manual 2007-09 and have a few questions I'd like to throw out there.

In a 2 person crew:

#1.

2.2 Putting the Ball in Play (Jump ball) (p.19) The manual states:

"E. Possession Gained in Team's Backcourt.
1. Umpire will move with the ball to become the Trail.
2. Referee will move into Lead position. See Diagram 2-4"

My question is do you guys/gals follow this mechanic on a jump ball? I am not sure if I've ever seen that done here in Texas. In virtually all cases I see the R take the Trail position regardless of possession gained in Team's Front or Backcourt.


#2.

2.2 Putting the Ball in Play (Free Throws) (p.23-24) The manual states:

Lead Official:
"6. Watch the first space on the near lane line and all the spaces on the opposite lane..."

Trail Official:
5. Observe the thrower and top two spaces on the opposite lane line..."

(Diagram 2-12 is used to illustrate)

Question: Since the players were moved up one space for the 08-09 season, is this coverage still valid? What is the correct coverage if it's not?


#3.

2.3 Court Coverage (Three Point Try) (p.30) The manual states:

"6. When the Lead Official signals a successful three point attempt, the Trail official shall mirror the signal."

Question: I believe that I was told that the Lead should only signal that the attempted shot is a 3 point attempt --Not signal if the basket is good. I was told the Trail should pick up the attempt and signal if the basket is good. What is the correct mechanic for the Lead?

Appreciate the help! Again I am in the great state of Texas if it helps rule clarification.
