Throw-in Mechanics Crew of Two (Co2)

[Zoochy]

I quickly looked in the Officials manual. I can't find it and I'm tired of looking for it.
The ball goes Out of Bounds, on the sideline, below the Free Throw Line on the Lead's side. The Lead administers the Throw-in by bouncing the ball to the Thrower. The Lead raises their arm to chop in the clock. Does the Trail mirror raising their arm to chop in the clock?
What if the throw-in is on the End Line? Would the Trail raise their arm to chop in the clock?
For a Co3, does the Trail raise their arm for Throw-ins by the Lead?
Does IAABO have different Mechanics than NFHS on these situations?

I worked NFHS and NCAA Men's basketball. I raised my hand in the Trail in 2-man games and 3-man games.

I'm pretty sure it's in at least the Men's CCA manual. I always paid more attention to that than the high school manual.

Same for NCAAW, and for HS here

I don't know why an IAABO instructor stated that it is not appropriate for the Trail to raise their hand

[Mark T. DeNucci, Sr.]

I do not remember how many years ago when the NFHS adopted the T 'chopping' in the Game Clock in the Situation described but I do remember that it was adopted.

P.S.: But I do not remember why I walked into the bathroom.

Because it says so in the IAABO manual.

As my Mom used to say, "Because I said so!".

Only the administering official (under normal usual circumstances) chops it in.

And we were just reminded of this in a "You Make the Call" video play summary last week.

... You will notice both the Lead and the Trail have their arms raised to start the clock. This is not an approved IAABO procedure. Based on the IAABO manual, the administering official should be responsible for signaling when the timer should start the clock.

I have no idea what the NFHS manual says.

I believe that Zoochy is an IAABO official.

C. The administering official then:
4. Raises the arm farther from the thrower in the stop‑the‑clock signal.
B. The non‑administering official is responsible for the following:
1. Providing coverage for all players not in the vicinity of the throw‑in
2. Ensuring substitutes are properly admitted

When the Lead administers a throw-in and the throw-in location/situation makes it difficult for the timer to see their signal, the Trail has the option of mirroring the Lead's start-the-clock signal.
Why make it an option? It should me mandatory
And Yes BillyMac, The reason I am posting this is because of the "You Make the Call"

As officials we want the game to be administered properly and that includes the timing of the contest. Why would the Trail official fail to do something which is going to help the timer? The officials on the court should strive to make the game as easy as possible for the table crew. Any assessor who thinks otherwise is foolish.

95% of the time when we IAABO officials use this option it’s either when the inbounds is on the endline, most often opposite the table, or in the last seconds of a period, especially in a close game.

In all of these cases we are instructed (locally) to inform the timer to watch the trail official.

Most IAABO observers are aware of this option and would actually disapprove if the option is not used in such circumstances, thus implying some type of mandate.

What does the NFHS say about such?

Right out of the Manual on Page 74 (Sorry, cannot embed the photo).

The Lead has primary on-ball coverage when the ball is below the free-throw line extended opposite the Trail. When a throw-in occurs on the sideline opposite the Trail below the free-throw line extended, the Lead administers the throw-in using the boxing-in method by bouncing the ball to the thrower. This means the Lead and Trail will not have to switch or move across the court to administer a throw-in below the free-throw line extended.

In order for the Lead to administer the sideline throw-in, significant coverage adjustments must be made. The Lead must move closer toward the sideline before bouncing the ball to the thrower to ensure a proper visual field that includes the thrower and throw-in plane. The Lead should also get deep (move back away from the end line) to increase the field of vision and see secondary coverage of post play on the low block (MechaniGram).

With the Lead focused nearer the throw-in, the Trail must move off the opposite sideline and onto the court to officiate all off-ball action, including action in the lane area. The Trail must be aggressive if an off-ball foul in the lane is detected, moving toward the foul to close the distance. The Trail is also responsible for mirroring the “start clock” (Signal 1) of the Lead.

As with all throw-ins, the Lead and Trail should make eye contact before the Lead bounces the ball to the thrower.

Keep in mind the Lead administers throw-ins below the free-throw line extended when the ball goes out of bounds on the Lead’s side of the court. If the ball goes out of bounds below the free-throw line extended on the Trail’s side of the court (opposite the Lead), the Trail administers that throw-in. There is no need for the Lead to come across the court to administer that throw-in because the Trail would also have to cross the court to apply boxing-in principles.

Thanks JRutledge.

These three paragraphs seem to specifically deal with a sideline throwin by the Lead below the free throw line extended, another good time to use the Trail to chop in the clock (and it doesn't look optional, rather it seems mandatory).

I wonder what the NFHS says about other throwin situations where it is difficult for the timer to see the administering official?

This has nothing to do wth the Trail mirroring the Lead to chop in the clock, but with boxing in.

Several years ago IAABO made an exception to always boxing in on a throwin.

IAABO Manual
Page 297
Frontcourt Throwins
2. The Lead has the option of
administering from either side of
the thrower, whichever provides
the best court coverage.

I've only used this exception a few times as the Lead on a front court endline in the very far corner (almost on the sideline) when I thought that there was going to be one, or two, competitive matchups in the lane.

[Raymond]

I just based it on the three-point line.

I do not now when in NF or general mechanics you did not box in the players. This has been my method for as long as I can remember.
