I have been helping an Essex junior with his game and he has been coming on well. Today all the Essex kids had a teaching sesion with their Leadbetter and John Jacobs trained coaches. The kid I am helping has been beating the rest of the kids. They had a look at his swing today and this is what they came up with. The coach said that his head was behind the ball at impact and they said " THE HEAD "MUST" BE AHEAD OF THE BALL AND CLUB FACE AT IMPACT". I can not for the life of me get my head round this. I am confused . Am I missing something? What do they mean? Please clarify.
