I still don't like Rogers as a selection so much. He's not quite been the run machine fans and journalists make out. I think his chances of replacing Cowan are small, given Cowan played well in England last winter for Aus A, and showed improvements during the India tour. I'd guess if Rogers comes in it will be as reserve batsman ahead of Khawaja (who will have been royally screwed by lack of playing time), or ahead of Watson. Steve Smith is the other one. I'd be surprised if the selectors abandoned a young player who might have just turned a corner to turn instead to Rogers. We'll see.
But I like Haddin's case, particularly now that Watson has stepped down as vice captain. Seems like the keeper will be the vice-captain this tour, it's just a matter of whether it's Wade or Haddin. Haddin gives an extra right hander to annoy Swann, and I personally think he's the better player anyway.
Harris will probably get a run. I'd rather see him in the XI ahead of a guy like Starc who is still pretty raw.
