|Zach Mercer: should be starting|
I would have had Mercer - playing out of his skin this season - starting at number 8, but his entire omission from the matchday squad means that England will have no proper back row cover on Saturday, with either one of Courtney Lawes or Maro Itoje probably having to fill in at flanker if required.
Let's be clear, Lawes/Itoje at flanker has never worked previously for England and there's absolutely nothing to suggest that it will be successful this time against what is probably the most effective back row trio in world rugby.
I had hoped that Eddie Jones might have learned from previous experience. It seems I was mistaken.
