bucky wroteIf doing one act that can't be ignored b/c it is an attempt to draw attention results in a technical, then why can't another?
Why? Because the casebook play is associated with this rule:
A player shall not: Illegally contact the backboard/ring by: Intentionally slapping or striking the backboard or causing the ring to vibrate while a try or tap is in flight or is touching the backboard or is in the basket or in the cylinder above the basket.
bucky wroteNFHS case 10.4.4 Sit A Comment: A player who strikes either the backboard so forcefully it cannot be ignored because it is an attempt to draw attention to the player, or a means of venting frustration may be assessed a technical foul pursuant to Rule 10-4-3.
