Since Ponting slipped down to number four, the first drop position has been flimsily guarded.
Khawaja had a bit of a turn there, then Marsh had a bit of a turn there, and then in the WIs Watson had a bit of a turn there as well. Seems pretty unstable.
So what do we do?
Leave Watson there?
Move Ponting back there?
Give Khawaja or Marsh another turn.
Move Clarke or MHussey up there?
Give Forrest a turn?
