Personally I think the only spot that is really up for grabs is between Horne and Mitchell. I tend to think Mitchell might start against England for his kicking. I don't think Speight is in the frame and I tend to think Tomane will be overlooked because his defence is far inferior to Horne and he doesn't have the kicking game of Mitchell.
Douglas needs to be more physically abrasive but I don't really see his position in danger. Everything went better when our starting locks were on the field than our finishing locks. Out of that though, I thought Skelton did a few good things in his time on the field. I don't see him taking a starting jersey though.
I think Giteau is pretty locked in as a starter. To'omua will remain on the bench.
With Fardy, Pocock and Hooper all being 80 minute players I think we'll continue to have two locks on the bench with Mumm or Fardy being the backup number 8 option.
I'd be surprised if Cooper gets the starting spot against England even if he has a blinder. I think Foley did enough and Cheika won't be disappointed by his performance.
Cheika and co have said multiple times that they've been training with these two XVs since before the USA test. I don't think selection decisions are as open as some people may suggest or wish. It seems that mostly those thinking that is the case do so because they want someone who isn't in the team to be there in place of someone who already is.
And conversely, those who think there will be no/little change probably do so because they favour someone already there over an alternative who might be playing better rugby.
IMO, players like Phipps, Cooper, To'omua, Mitchell, Speight all have an opportunity to show they are in better form than their counterparts who started against Fiji.
I also disagree about Big Will having some good touches when he came on. According to Forcefield, he was involved in two rucks only and one or both was/were ineffectual. He didn't make any damaging runs with the ball, I think averaging 1m per run, and he didn't put any supports away. What exactly did he do? I would really like to see him live up to his promise and hype because atm our lock stocks are very thin on the ground and none of those over there are really top notch.
