Overture....then I hit a flat note

[Nevadaref]

Franktown,
Why do you feel that YOU missed this call? In fact, your partner missed it.
You could have helped with the violation, but it was the R's PCA.

Let's review:
You were the Umpire; he was the Referee. One of the two jumpers violated during the jump.

Officials Manual page 18:

2.2.1 B5
Jump Ball
Referee (or designated tosser):
Have primary responsibility for action of jumpers.

So you were still perfect two seconds into the game.
