These mechanics are very rarely seen in gameplay, and both can help a lot.
The first one is stealing the ball from teammates, in-game they're trying to stall the game by keeping the ball away from everyone.
However, while doing this, remember that friendly hitboxes are not compensated by lag when they're moving, so you'll either have to use the whip to catch them easier, or hit ahead of them.
You can only steal the ball from your teammate if they've held it for more than 45 seconds.
The second feature is for heavy only, which can be used for being a "goalie", defending the goal where the ball has to be thrown in. To do this, just keep your gun revved up.
