Garret, as I said in my first post, this now leads to a debate on which technique is best and something that I wanted to avoid.
Firstly, you are misunderstanding what I am saying. I am certainly not recommending that he plants his front foot. A forward press certainly does not mean a huge plant of the front foot across your stumps before the ball is bowled! It is a small movement positioning the front foot straight down the wicket, not closing off your stance at all.
Can it work against bowlers of 80mph? I can infact state that it even works against 90mph,having faced NTini, Simon Jones, Franklin Rose etc using this method. Sorry, thought it might illustrate that I am indeed speaking from personal experience not just throwing about untested advice.
The point is that the beauty of batting and cricket is that you can achieve the same result by using different methods. The most important thing is that the player uses the method that is appropriate to his technique and style of play. If not, we would all be batting the same way and how boring would that make cricket.
