Assisting Question

[random.hero]

What really counts as an assist?

If the ball is laying on the ground and you bump it into the next zone and someone from your team picks it up is it an assist?

If you have possession of the ball and roll it out of your robot into the next zone and your team picks it up is it an assist?

Or, is it required that the ball not touch the ground in between robots and must be tossed or handed directly to the next robot?

Thanks in advance for any info.
