Drills are part of every coach's vocabulary. They are frequently used in sport to teach technical and tactical skills. To some coaches, their drills are their prize possessions; they reflect their innovative and artistic abilities. Experts have an extensive repertoire of drills they use in practice. Some of our experienced coaches have specific names and purposes for their drills. "Eventually, we had about three or four style drills. We would have walk throughs, which we called dry drills. We would have coaching situations in which we had "Stop, stop, stop, instruction" drills which we would do before we warmed up. Then we would have what we called very competitive drills, so we would get them maxing out, and then we would have scrimmages in which we weren't allowed to coach. We just refereed, tried to leave them in. Later, we would get to other drills, we would have what was called the drink drills, which were time-out drills. They would go and get a drink and be back in a minute, and they had to be in a huddle. (BB4)
