Anything I render my decision on is what I would consider a judgement. Maybe it's my baseball mentalitybut, I'm feeling like nearly everything in the game of basketball is a judgement call.
No matter what I say, it is not going to move the shooter's foot. But it is my judgement whether the shooter's foot is on the line or behind it and therefore it is my judgement whether this is a three-point attempt or a two-pointer. Not being allowed to use instant replay, an official must make that judgement.
Every officials manual I've looked at assigns particular sections of the floor and thereby, particular section of the three-point arc to an individual official. Shots at any ONE point along the arc are the responsibility of ONE official. See your mechanics manual paragraph 205, diagrams 7 & 8, for 2-man and diagrams 37, 38, & 39 for 3-man.
If it is your section of the arc, I will be expecting you to call it. And I'm not going to correct your call to all of the audience if I think you got it wrong. Egregiously wrong? Okay, I will probably offer you some help. BUT I WOULD NEVER STOP THE CLOCK AND YELL TO THE TABLE THAT "MY PARTNER WAS WRONG. THAT WAS A TWO POINT SHOT." and then expect to just continue on.
Your authority on the court is just the same as mine and I'm not going to over-rule your decisions. If you need my help, I'll do all I can. But I am not going to over-rule your judgement of foot location.
Quite frankly I would not want to work with a partner that felt they could wantonly over-rule me with no consideration of my responsibilities/decisions. That doesn't inspire any kind of team spirit or partner respect. And that means you don't do a good job for that particular game.
