lively ball

[Nevadaref]

If the ball doesn't bounce within the legal specifications, either make it legal or replace it. You don't need to consult the coach.

Rule 1, Section 12
ART. 2 . . . The ball shall be inflated to an air pressure such that when it is
dropped to the playing surface from a height of 6 feet, measured to the bottom
of the ball, it shall rebound to a height, measured to the top of the ball, of not less
than 49 inches when it strikes on its least resilient spot, nor more than 54 inches
when it strikes on its most resilient spot.
NOTE: To be legal, the air pressure which will give the required reaction must be stamped
on it. The pressure for game use must make the ball bounce legally.
ART. 3 . . . The home team shall provide a ball which meets the specifications.
The referee shall be the sole judge of the legality of the ball and may select a ball
provided by the visiting team.
