The player who had to leave the court would not be allowed to come back onto the court until one of the following events occurs: the offense scores a basket; the offense takes a shot and misses and the defense grabs the rebound; the offense turns the ball over (steal, intercepted pass, travel, ball thrown out-of-bounds, any other rule violation).
In the case of a player on the offense committing a foul when his team has a 5 to 4 player advantage, the player who committed the foul would have to leave the court and the other team would then throw the ball in with a 5 to 4 player advantage.
I like it! The last two minutes of a basketball game is torture to watch with all the intentional fouls.
I would like wider use of the Elam Ending. At four minutes left the clock is turned off and a target score is set to the leading score plus seven points. First team to that score wins. It eliminates the incessant fouling and timeouts in the last few minutes. The leading team still has to score to win instead of trying to run out the clock. I thought it sounded ridiculous when I first heard of it, but with it the end of the game is still basketball instead of alternating muggings and free throws it is now.
I like the idea of a penalty box in BB - it would certainly cut down on fouls, given that the team would have to play 1 short for however long the penalty is for.
Raising the basket sound like a good idea too. And for crying out loud, start calling for traveling and double-dribble again, along with charging. They let the guy with the ball run over everyone, take 3 steps, palm under the ball when laying up - it’s ridiculous.
