Why just Lydiate or Croft? Warburton at 6, Tipuric at 7, or SO'B in at 6 are some more alternatives. My picks are SOB, Warburton/Tipuric (swaying towards Tipuric, even after Warburton playing so well) and Faletau in order to add some go-forward. But I agree that Lydiate wouldn't be my pick for now. He's a fantastic player, but the balance of the pack needs to be redressed - the pack is fine defensively, but needs to add some carriers. (If they were on the tour, I'd suggest to just add Morgan/Beattie and leave the rest alone. They can carry for a team. And 6. Lydiate 7. Tipuric/Warburton 8. Morgan/Beattie would be brilliantly balanced.)
