Yell "bounce" rather than out when communicating a possible out ball

While the ball is in the air, if a player yells “out,” “no,” “bounce it,” or any other words to communicate to
their partner that the ball may be out, it shall be considered player communication only and not considered a line call.

Too many posts on the Forum complaining about a partner calling out before a ball has bounced and teams getting confused that it's partner communication. Personally I think the rule currently is clear cut but it causes many questions and problems if you read the Forum or Ask the Referee Facebook pages.

When a partner communicates a possible out ball that ends up being in. Opposing teams don't understand its partner communication
