I didn't say that.
I was replying to why we haven't brought back other older players like Mowen and Fardy (because Fardy has been discarded and Mowen hasn't made himself available).
The actual reasons why we should pick him:
We have our two first choice outside centres injured in Reece Hodge and Tevita Kuridrani. Our third, in Kerevi, is injury prone, coming back from injury and also known to not perform in high pressure situations (like England).
So this leaves Naivalu, Folau and Petaia. All unproven at this level at outside centre. Petaia shows promise but he is literally just a kid. Folau is incredible but an outside centre he ain't. I actually like Naivalu here, but as I said unproven.
AAC (Adam Ashley-Cooper) can play pretty much any position in the backs, he's Australia's third most capped player ever so probably has a bit of wisdom to share around (perfect mentor for our next prodigy in Petaia hey?).
Yeah he's 34 and probably lost a bit of pace, but he'd be easily one of our top defenders. And if Folau or Naivalu go down injured, what happens then? Who comes onto the bench?
