Cameron White hasn't been seen in the Test arena since his unsuccessful bowling all rounder stint, couldn't even make this Test squad. Hes always been in the ODI side for his batting. And Watson was partly to do with Hughes technical flaws and also to do with needing another bowler to backup the wayward Johnson. So that is more desperate times calls for desperate measures than flexibility. If they want to show it then moving Hughes or Smith to 6 would go a long way.
