Surprised nobody has commented here!
Wales have changed 6:
Liam Williams (Scarlets), Alex Cuthbert (Cardiff Blues), Jonathan Davies (Scarlets), Jamie Roberts (Racing Metro), George North (Northampton Saints), Dan Biggar (Ospreys), Mike Phillips (Racing Metro), Gethin Jenkins (Cardiff Blues), Ken Owens (Scarlets), Rhodri Jones (Scarlets), Luke Charteris (Perpignan), Alun Wyn Jones (Ospreys), Dan Lydiate (Racing Metro), Sam Warburton (captain - Cardiff Blues), Taulupe Faletau (Newport Gwent Dragons).
Replacements: Richard Hibbard (Ospreys), Paul James (Bath Rugby), Adam Jones (Ospreys), Jake Ball (Scarlets), Justin Tipuric (Ospreys), Rhodri Williams (Scarlets), Rhys Priestland (Scarlets), James Hook (Perpignan).
Some good things, but I don't get why you'd give Rhodri Jones and Ken Owens a go whilst not giving Paul James a go? Why not change the whole front row and seeing as Wales will perhaps be weaker scrummaging-wise at Tight-head and Hooker, why not support that with Paul James who has looked excellent so far?
I also don't understand why you wouldn't give Tipuric a run. The last time Wales played properly well was with Warburton and Tipuric together - yet we haven't seen that replicated since.
What does Liam Williams offer which James Hook can't?
Lastly, did Jake Ball deserve to go back to the bench?
