Bowling the same ball six times is not consistency

A bowler who lands every delivery on one spot has told the batter everything he needs before the second over.

Consistency is the most abused word in bowling coaching. It gets used to mean landing the ball in the same place, and landing the ball in the same place is, past a point, the easiest way to become predictable.

A batter facing a bowler who hits a single spot builds a picture very quickly. Three balls tells him the length. Two more tells him whether it holds its line. From there he can pre-commit, and pre-committing is worth an enormous amount, because the whole difficulty of batting is the fraction of a second spent deciding. Take away the decision and a decent player will milk that bowler for four an over without ever hitting a boundary, which is a slower kind of defeat but a defeat all the same.

What you actually want is repeatability of a corridor with variation inside it. The ball should be arriving in a zone roughly the size of a dinner plate on a good day, but the ones landing there should not all be the same delivery. Change the seam angle. Change the wrist. Bowl one a little fuller with the same action so it looks identical out of the hand and arrives half a metre further up. The batter's picture never stabilises, and the corridor keeps him honest while the variation gets him out.

This is why the accuracy charts that clubs love are only half a measurement. A pitch map showing a tight cluster looks wonderful in a review meeting. It cannot show you whether those deliveries were the same ball. Two bowlers with identical maps can have completely different records against the same batter, and the difference lives in information the map does not carry.

The practical consequence is about nets. Net bowling rewards the exact habit that fails in matches, because the bowler with no fielders and no plan defaults to hitting his spot over and over to feel good about himself. Give him a target and a constraint. Six balls in the corridor, no two the same, and he has to name each one before he bowls it.

I would add one caveat, because the argument can be taken too far. Against a genuinely aggressive batter early in his innings, monotony has value. He will try to force the issue and you want him doing that from a length he has seen. Consistency as a phase, not as an identity.

Bowlers who never vary do not get hit. They get used.
