It had more do with the fact as we have discussed before that he was rotated up & down the order & wasn't given a set role like in this current series.
I really cant see how you can find much if any fault in anything Dussey has done this series. Ok only one innings he did the work. But except for Watson he has been the 2nd best batsman in a series where non of the top 7 have played to potential. So he can only getter better from here going into the WC.
First off that is such a poor excuse. If hes not capable of adapting then he shouldn't be in the side. Look at Marsh and Ferguson both were put in spots they haven't played much in and both have performed. And second he has been given a role, that has been to play at number 6. Only one game has he been moved away from that position so I don't know why you are using that excuse anyway.
As I said the reason Dussey was dropped was not going on with his starts. He has only gone on once this series with the start so hes still got to prove he can go on with the starts.
As i said. The selectors are settled on the idea that want the keeper opening with Watson. So if Haddin where to get injured they want to keep that formation, instead of picking another pure opener like Marsh/Warner in the squad or asking Clarke to open.
No idea why you keep bringing this up and even then it's wrong. Paine was picked for his keeping nothing to do with him being an opener. And if Paine wasn't there then Marsh would open and Hussey would take the gloves so where is the problem apart from a part time keeper? The only way your point with be valid was if they were deciding between a keeper that didn't open and one that did but they weren't as Paine was always seen as the backup to Haddin and the number 3 in Wade opens anyway.
As I said before though, I don't mind Paine being in the side just use him as a batsmen as well as a keeper else pick someone you can like Wade who would give us the option of adding an explosive number 7 rather than having that spot wasted as a keeper only replacement.
Ponting injury was already seen as long-term yes. But Hussey played in the first ODI which was Jan 16th when the selectors probably already had their 15-man squad decided, then he got injured & at that moment nobody was sure how long he would be out for.
By the time they named their WC squad they knew exactly how long Hussey was out for heck they named their squad a day early, that doesn't sound like a team that has no idea how long he was out for.
