It wasn't just Hooper and Cooper, however I would most certainly have had both of them in the squad (BR I am aware of your low regard for Hooper, which of course hasn't come about just this year) I would also have taken both Lonergans, Neville, Samu, Ikatau and Hodge (and, of course, Rennie!!!)
This may seem like sticking with the past, but this is the side that has been building towards the WC, and while the results have been mixed, they have been better than this year.
The time for renewal is AFTER the WC, not on the eve.
Who would I have left behind? Uelese, Arnold, Kemeny, Gleeson, IFL, Donaldson, Vunivalu and Jorgensen, yes and EJ (Eddie Jones) (Eddie Jones).
