Being coached to be able to bat in all conditions - rather than just favourable ones - doesn't just cover batting locally on the occasional testing pitch.
It gives you the tools to bat in the different conditions experienced overseas as well. Or have we all forgotten how totally at sea some of our batters have looked in English conditions in recent times?
And it also underpins one of the underlying foundations of batting, which is having a good defence - from there you can build a solid and extensive batting technique.
Justin Langer continued to point this out. So many batsmen getting out when they were anchored to the crease. No forward nor backward movement. This can only indicate one thing, poor technique.
