Interesting selection, and I agree with some of it. Craig Mitchell at 3 is a good shout, because he needs gametime after returning from injury. He'll be important as backup to Adam Jones, and we all know Adam Jones is world class, and can slot straight back into the team no problem. Worth giving Ryan Jones more gametime at lock, because he's probably gonne have more gametime there off the bench than whoever the other backup lock will be (probably Charteris). I'm not sure about Turnbull, if there really a need? He's had quite a severe dip in form since his outstanding first half of last season. We can also play Ryan Jones or Delve at blindside if needed, or even move Warbs across to accommodate Williams or Tipuric at 7. I'd prefer to see Lydiate continue at 6 alongside Warbs and Faletau so they can continue to build as a unit on their excellent display v the BaaBaas. Turnbull's time will come, but I don't think he'll be making the WC squad this time.
Knoyle would be good at 9, but I think Gats will go with Phillips to try and get his form back. Not sure about a Henson - Scott Williams centre partership either. Henson is out of practice, not the best partner for an inexperienced youngster like Williams to play against England in HQ. I think it would be a little unfair on him. I also think we need to find a genuine centre partership in these warm-up games, and that will include one of Roberts or Davies imo, so get one of them playing alongside Henson for at least a half in each game. Gatland also needs to decide where he sees Hook playing come WC time, at 10 or centre and give him a run in that position during these warm-ups.
Finally, I don't like Stoddart at fullback, but then maybe he needs gametime to see whether he can be a bench option to cover the back three. I feel Byrne needs gametime aswell, overall we're in a bit of a pickle at fullback, mostly because Gatland simply shifted Hook back to 15 whenever there was an opportunity to try someone new like Stoddart, Halfpenny, Priestland or Tovey.
