Goughy,
Thanks for the answer. It does come down to delivery stride.
Most people land on the right and then onto their left, lifting their right foot before the ball is released.
If your bowling off the wrong foot, then in some sense you land the left, then the right, and lift the left before before bowling.
It isnt just an academic question, my 12 year old bowls this way.
I did go to a coach but he ended up suggesting that it may be easier to get him to bowl left handed, as his feet just want to do what they do.
He actually generates a reasonable level of accuracy and pace form his action, and it looks quite a smooth action.
Had another coach look at his action, he commented that his body, arms etc are in good position.
He then mentioned that a couple of first class bowlers had bowled off the wrong foot and that fixing his feet would take a lot of work.
Anyway thanks for responding to my question
