I think we need to get over the allrounder obsession. We are not going to uncover a Freddie flintoff, even freddy himself was only a top allrounder for a couple of years. For the moment I would go with:
Warner
Rogers
Khawaja
Bailey
Clarke
Watson (Smith if it's a turning pitch)
Haddin
Siddle/Cummins/Hazlewood (Those two are bowling well in Zimbabwe)
Patto/Starc/Bird
Harris
Agar/Ahmed (who just took two 4-fa's vs Zimbabwe)

Hughes is not only flawed against the short stuff, but hopeless against spin. Watson just isn't good enough to open, he's suspect on his legs so guys like Anderson, Steyn etc just smile when they see him coming, they know he'll be out in about 30 balls. Warner is a wildcard, he can take a game away from you in a day, but he needs to be consistent. Khawaja looked good last night, I really hope he can forge a spot for himself. Agar has come back to earth. Rogers isn't great but I'm not sure who could replace him, no-one is screaming out to be picked.
Clarke is not a great captain, he had one of the best runs with the bat ever seen but that has dried up and now we're seeing just how reliant we were on he, Ponting and Huss to score runs at 4,5 and 6. Right now I look at our 1-6 and really only see Clarke as a guy who can make a big score. Even Haddin's spot can't be safe, with the angry midget looking to work his way back in to the side. I hope Shaun and Mitch Marsh get a game in the next Aus A match vs STh Af A as I think Shaun still has something to offer.
