I'd go back to Matthew Wade. 25 as opposed to 35. We need to build a team. Wade has time to get better and I'd say his batting is the equal of Haddin's. Get him to train with Ian Healy flat out for the next 18 months and tell him his spot is safe as long as he does the work off the pitch. I agree with Steve Waugh a bit when he said we need stability, I agree we need stability but guys should still have to earn their place and know their is pressure on them from others outside the team. I would think guys that have the potential to improve, and a work ethic and time on their side should be picked. I don't think Haddin is awful, just at 35 may have run his race and its time to move on.
Watson injured to often, seems to chock full of himself, has never seemed willing to do the really hard work.
Khawaja has had his chances and needs to do what Hayden and others before him have done, go back to shield level and make buckets and buckets of runs over at least two years before he is considered again.
Any way will be interested to see what happens for the last test.
