As England crumble to serious pace in Australia and India prepare to take on the even more serious pace of South Africa, Sanjay Manjrekar talks of why the initial back and across movement so beloved of modern batsmen is a cardinal error:
With a big initial back-foot movement, you are committing yourself completely to a delivery of a particular length, short. So when the ball is short you seem to have plenty of time to play it, but when it is full you are invariably late on it, and if your luck as a batsman has run out, as Cook found out, that full, seaming ball will come early in the innings, hit the right spot and get through your defence.
As a batsman you ideally want the smallest trigger movement, so that you are prepared for all kinds of lengths and lines. In this Ashes, Michael Clarke, Steve Smith, Joe Root, and also Ben Stokes, have shown that kind of technique, with no pronounced prior commitment to any length. Because of that they have looked much better positioned to balls that are pitched up. Batsmen make the initial move in the crease because that way they feel they are setting themselves up for the challenge. Very often it's just a matter of "mental preparedness". Some do it to be in a good position to face a particular kind of delivery that they feel they are susceptible to.
My view is that if you have to move your feet before the ball is released, it's better to have a front-foot movement instead of a back-foot one: looking to move forward before the ball is bowled rather than back. That way, you are better prepared to handle the ball that gets most batsmen out in this game - the one that is full in length.
