It’s a Trap!
I hate to break it to you but a ‘trap’ in Dodgeball doesn’t happen as often as you think. Just look it up in our Dodgeball rulebook and you’ll find that a ‘trap’ is a ball that is caught and hits the ground or wall at the same time. Like, the EXACT SAME TIME. This is then considered a dead ball and no one is eliminated or comes back on.
One way to look at it is if the ground or the wall wasn’t there, the catch would have been easily made by the player. The ground or wall actually interfered with the player catching the ball.
