undertaker, I'd love to know what more you reckon Wade has to do? Killing it with the bat and keeping very tidily. Would clearly improve the side. Nevill would also be an improvement.
Long post disclaimer...
I know that Ponting and Hussey have been under a lot of scrutiny recently. However, barring injury to either player, their performances in the first two tests of this series will definitely assure them of a position in the side until AT LEAST the end of the 2012/13 summer, as there are barely any middle order batsmen in Sheffield Shield that are putting the world on fire. There's a high chance that they'll also play in the 2013 Ashes, as I mentioned in a previous post that the selectors have learnt from last summer that blooding new players and untried combinations in a major tournament doesn't work. Also, Marsh, Khawaja, Hughes have been extremely inconsistent and are still relatively new to test cricket. I can see the selectors persevering with Cowan/Warner as openers, as there's a lot of potential there. Warner just has to calm his nerves and snap out of the T20 mode when he bats in test matches. 2nd test vs NZ in Hobart showed us what he's capable of in the highest form of the game. The top 6 that I can see the selectors leaning towards is:
Cowan, Warner, Clarke (c), Ponting, Hussey, Watson (vc)
Now, to the part in bold which addresses your question...
Regarding wicketkeepers, I would've said Paine was next in line as Haddin's successor (since he has played tests), but given his recent potential career-ending injury, this is a blessing in disguise for Wade. Being the same age as me (which I didn't realise until I looked up his statistics), Wade just has to be patient and more importantly, keep performing well with the bat like Gilchrist was in the late 1990s before he succeeded Ian Healy. It will be a matter of time before the heat is on Haddin, and it certain went up a few degrees after that shocking drop catch towards end of play. The temperature will go up even more if Wade starts performing with the bat. At his peak in the test team, Gilchrist showed how vital it is to have a good batsman at number 7 in a test lineup (the last "recognised" batsman in the lineup before the tail). Haddin always had potential with the bat, but is notorious for throwing his wicket away when the pressure isn't on, but trying an unnecessary shot. His wicketkeeping has been on the decline for the last 12 months. Wade averages about 40 in FC, and if he can get it towards 45, that's very good for a wicketkeeper.
The same could be said for Steve O'Keefe. Easily the best spinner in Sheffield Shield cricket, the only one that averages under 26 I believe. Now, this is not a rebuke towards Nathan Lyon. Lyon has already done a fair bit more and turned the ball a lot more than Nathan Hauritz did in his 2 yrs in the Australian team. However, O'Keefe is definitely the #1 option, and also would be an extremely handy batsman at #8. With Siddle at #9 and Pattinson at #10 (both of whom are capable of scoring runs and occupying the crease for extended periods of time (e.g. Siddle in 2010 SCG test)), that's 10 players in the lineup who are all capable of scoring runs and occupying the crease. The 12 that I would love to see after this summer is:
Cowan, Warner, Clarke (c), Ponting, Hussey, Watson (vc), Wade (wk), O'Keefe, Siddle, Pattinson, Hilfenhaus or Harris as #11 with the other being 12th man.
In form and at full strength and fitness, that is one hell of a side that has the potential to get us back to #1 and also reclaim the Ashes. Clarke needs to go to #3 as the most important batsman in the side. Watson at #6 allows us to maximise his bowling talent (which is something I also address in a previous post). And I also mentioned this earlier, but the omission of Johnson has, to a very large extent, allowed Siddle and Hilfenhaus to build pressure and it's no surprise they have bowled a hell of a lot better this time around than when they were bowling in tandem with Johnson, who alleviated the pressure on opposition sides who reveled in his crapshack bowling.
Btw, thanks for asking me of my opinion. I didn't know whether or not you were being sarcastic or genuinely wanted to know (given all the piddly arguments between members on this thread), but I admit that I'm no "expert" on cricket (like ESPNCricinfo calls ppl like Harsha Bhogle) - I'm just a university student studying Masters degree who's been following the game passionately since 1995 (which is around the same time I started following League as well).
