It might be Maxwell who gets turfed for D.Hussey, and so he should to be honest. He had a pretty ordinary game vs Pakistan, and his fielding and bowling are not enough to make up for that extra assurance Dave would bring in the middle order. In fact I rate their bowling about equal, and if Doherty and Hogg are going to both play, then Maxwell's bowling is basically irrelevant anyway. People can say 'X-factor' until they're blue in the face, but Maxwell just isn't that good a player yet.
Drop Maxwell for Hussey and you get Watson + 5 proper batsmen + 1 keeper + 4 bowlers. The way it should have been from the start! Maxwell and Christian just can't do one skill well enough to deserve a spot IMHO. You can see it when Bailey will not trust either of them to bowl anymore than they have to - and only Maxwell ever got promoted up the order.
