Absolutely agree with Hales in particular who struggles when teams bowl a consistent off stump line with slips in place. If Hales worked day and night and rectifying that weakness (which he may never successfully do) it would be at the expense of working on what he is very good at - one day cricket.
What a load of rubbish. If you have defensive technical flaws they will always get exposed playing test cricket. Whether Hales played 10 tests or 100 he would never score runs against top quality test match bowling who hit the top of off stump often enough. Hales will know that himself and he knows where his strengths lie and the format of the game he needs to focus on.
Absolute piece of piss to get him out in ODI cricket then...
