There must be plenty of talk on defense, this is important. The following are the most important examples: a) The man adjacent to the ball must let the man on the ball know if he is backed up. b) If a man leaves to back up he must let the defense know he is leaving, so that they may shift. c) The man playing the ball must holler, “I’ve got-the ball”. d) If a man cuts, the defense man playing him should holler “man cutting” so that he alerts the rest of the defense for a possible switch. e) If a switch is necessary, both men call “SWITCH”.
