I am a fan of Bopara and have been for a number of years (having followed Essex closely), and always thought he would bat in England's top four, but was thinking more of a number 4 than no. 3. I think the England management like his positive approach, and it is widely acknowledged a no. 3 has to cease the attacking opportunity while being solid in times when a more defensive approach is required.
I think today Bopara was too intent on trying to make a positive/aggressive start in the Ashes, I'm not knocking his logic as such, he wanted to stamp his mark down and say strongly he was not going to be dictated to. However, he should have wound his neck in a touch, his reading of situations will no doubt improve, and I do think he has the game to succeed at three should he improve in this area.
He was far too loose for me today, the way he opens up his stumps does not bode well and is surely a technical issue that needs addressing as soon as possible.
Of course we have not accounted for nerves here, and with that perhaps he slipped back into a few bad habits. He generally looks a very cool customer, but will no doubt have been very nervous today.
