No reason for England not to slog a quick 50 then declare. We aren’t chasing down 170+ without Smith in under 2 sessions.
It's unlikely, but if we did then England and Joe Root has just thrown the ashes in the bin and will be criticised the rest of their lives for it. Not going to take that risk.
Warner and Khawaja are capable of scoring a run a ball 30-40, Wade can score quickly...
