I'm thinking only one of JOC (James O'Connor) & Beale will go. Both cover 10 & 15, though god help us if it comes to one of them playing 10. Then do you want a 12 or wing cover and it seems wing is the weakest as far as options with in form players go. JOC (James O'Connor) at his best is also better goal kicker and his defence is better, even on a bad day it is no worse than Beale's best. He has also played 15 more recently.
I am not really fussed on either and I wouldn't expect either in the 23 at this stage. But as far as utility value, JOC (James O'Connor) is the way to go.
Mate, we are good for wingers:
Horne in the form of his career.
Tomane is playing really well this year - especially in defence and the high ball something which he was criticized with in the past.
Mitchell - Apparently in very good form in France. His Grand Final performance was certainly world-class.
Cummins and JOC (James O'Connor) are the only ones who are below average and Speight has been consistently the best winger the last 3 years although having a quiet year this year, his last game was great.
Not sure why you think JOC (James O'Connor) "at his best" is any better then Cooper, Lilo or Foley "at their best". Both have had really good games at kicking for the wallabies, none have been consistent. Honestly they are all the same IMO - so you need to pick the one who is currently in form.
None of this works in JOC (James O'Connor)'s favour. I think he make the team for this utility value and international experience.
And If it is a choice between Beale or JOC (James O'Connor), then I would take JOC (James O'Connor) 99 times out of 100. Agree about defence, Beale has his moments on attack but is rubbish at the moment.
