Haurie is coming back from injury. Might be ready for SA. SOK obviously should have been there, but...
Beer will keep his spot. Not because he's ever done anything to deserve being selected in the first place, but his competition hasn't done any better. Very hard on Lyon to expect he could go over there and perform. The guy's simply not played enough to be physically capable of bowling the long spells required and then back up. Could be a fine bowler in a year or two's time, but his selection was so bad it's makes the selection of Beer and Doherty look semi respectable.
Harris, Copes, MJ, and Beer can get the job done if Johnson isn't having a shocker, but I'd back Watson and Pup to take more wickets than Beer.
On Huss I agree he looks very susceptible and may not see out the summer. I argued before the Ashes that one of the 36 year olds at least had to be pushed and hoped it would be him. Luckily for him he found some form and Kat got injured so it ended up being Kat that paid the price for Hussey and Ricky's poor form over the previous 18 months. I obviously don't want to see Marsh anywhere near a test cap, but I think the real longer term replacements in Lynn, Warner and Maddinson are at least another year away. Lynn looks like a fantastic middle order bat but he needs to prove it wasn't a one summer deal by coming out and making runs again this summer. Same deal for Warner, but you get the feeling he is a genuine opener and bringing him in means pushing Watto down a spot or two (which I'm cool with, but he might not see it that way unless his form starts to fail).
Maddinson is probably 2 summers away. I saw his ton against Qld and like noted above, he's just so compact and correct. Waited for the balls he wanted to hit and left everything else. Incredible to think he was only 18. But apart from his tons he missed out a lot. Like Warner it might not be a coincidence that his runs came when he opened and he didn't do much lower down. There's no need to burn the kid. Give him a couple of seasons and let him prove he can be a consistent run maker before we start talking tests.
One really left field suggestion though is playing Hauritz at 7 and pushing Haddin or his replacement up 1. Again saw his ton against Qld and it was at least as high quality as Maddinson's. He'd score a ton the previous game against SA and was looking every inch the batsman. His driving in particular was top notch. He has clearly worked damn hard on his batting and had made some very handy scores for the test side previously. If he comes out and makes runs for NSW again it could really open up the idea of playing five front line bowlers with Hauritz, SOK and Johnson at 7, 8, 9. Obviously Smith if he regains batting form, or Glenn Maxwell who looks a prospect could also fit the bill as 6/7 bat and 2nd spinner.
