We kicked it. Did I do enough?

GV. 3rd quarter. I'm Lead. Team A has a try from the opposite side of the floor from me.
Ball hits up top (I'm eyeing rebounding action) caroms, tip, bat, scramble, bat (last bat by A1 knocks ball into back court. A2 recovers ball in back court. Partner calls backcourt violation.

I get to my partner. "Partner, we had a try... did Team A have team control after the try?" He replies, "Yes, they had team control." Me, "you're sure?" Him, "yes".

I go to the throw-in spot and bounce the ball to the thrower.

After the game I tell him I think we kicked that one. He says that yeah, he guesses we did.

If it was a critical moment in the game, I would have probably slowed him down more, maybe review the sequence of events and try to get the correct outcome.

Any advice on language/techniques to get partner amenable to changing? Seems that in the moment he was committed to his call, and not eager to analyze.
