Just to pile on a little bit here:

Have you never heard of practice matches? You know, they aren't just for the teams to practice. What do you think the refs are doing? You talk to one ref before your first practice match. That ref passes the word around to check your robot crossing a defense that way. Happens more often than you might think.
