Warner is quite a conservative batsman in the longer form. I would be looking at him behind Usman as the next in line. Hughes problem is not his technique but his shot selection. His record is deserving of an extended stint, IMO he gets the Australian summer against the Kiwis and India then the following series abroad. Khawaja is an opener first and middle order player second, he is another option up the top of the order that has to be looked at. Watson needs to move down the order so he can comfortably bowl 20 overs a day. He is quite easily our number 2 bowler.
Khawaja
Hughes
Marsh
Hussey
Clarke
Watson
Haddin until Paine is ready
Johnson (just)
Harris
Copeland
Lyon
Ive got Peter Poo well back in the pecking order. For a bowler who has no variation and naturally drops short it is astounding he continues to get picked. He took 15 wickets in the Ashes series. Two 6 fas and then 3 wickets from the remaining 8 innings. Appalling.
Ben Cutting would be my next in line over the longer format. Hastings from Victoria is also an impressive individual. He bowled one of the best domestic spells I've seen against the Bulls. Toyed with Floros, whilst Lynn (in the 90s at the time) quipped he thought about giving his wicket away such was the hostility of the spell.
