Cricket Drill Demonstration
The practice should be setup as shown. Have one player as a wicket keeper and another as fielder.
The bowlers take it in turns to bowl, with the fielder calling if the ball was a good line (pitched in the cones) or a good length (pitched level with the red hoop).
If the ball pitches in the hoop then the ball is both a good line and length.
Focus on the target - the more focused the bowler is, the more likely they are to hit the target.
