Who makes the call?
 

Girls varsity -- 2 man.
Ball at A1 top of the key.
Lead is under basket left side, trail is opposite table side.
Ball swings to table side wing, then down to A2 for a spot up 3.

Ball goes in, trail signals 3, (and I don't know why but also verbals "3" to table).

Lead sees the score changed by 3 points and blows whistle as B team is dribbling in the backcourt. Changes trails call to a two. No discussion between officials.

CoachP alomost got his first T since 1999. Did I have a legit beef?

Pass on This One
 

Better bitter battles to bite off. As described, this was lead's call. And if my trail in that instance came up with a signal and I knew it was incorrect, I'd overrule him, too. Followed by having speaks with him at halftime regarding why he's guessing at something like that.

In most (but not all) areas, a 2-to-a-3 or a 3-to-a-2 is changed without discussion.

If the shot was from below the FT line extended on L's side, it was L's call.

Lead's call all the way. Good job by L to catch the error.

What would your beef have been? What would you have argued?

My beef was lead changed the call from behind left side lane and the three was from the right side corner. That was the side the trail was on, in front of home team bench. I saw a "3" from visitors bench and the trail saw "3". We had the best view. ;)

Really? That is leads call in the far corner? Seems better look from where trail was...oh well.

Plus, we were 8-0 until that night and we were getting our you-know-what's handed to us...

Coach, did you have a good view? Are you 100% sure the L was wrong? Or were you just arguing because the call was changed?

A lot of guys (and gals) pregame this, and will explicitly discuss having it handled exactly this way.

"If you see me get a 3 pt shot wrong, just blow the whistle and fix it. No need to discuss."

Ah, I see, the shot was from T's side, not L's. The only guy I know who's sneaking a peak at this shot from L is tref. :D

Both!

I am 100% sure, trail solidified it with signal AND verbal to the table as he passed by, so I assuming HE was 100%....

Yes. (Maybe my OP wasn't all that clear?)

Any film available, tape dont lie.

It was clear, but for some reason I got confused when reading it. After you repeated it, I re-read and it seemed clear.

As tref notes, too, I'd check the tape. It's possible the L was right and the T (and you) were some how obstructed. Either way, I'll bet they had a nice little chat in the locker room.

The bolded part is confusing me then. Was the trail "opposite the table"? That's how I read it.

Ah, there it is...!

Trail is tableside (right side). Lead is underbasket. (leftside)

Less confusing this way.
