I've never seen the "two opensides" work for an extended period either.
And I can't see why we would try it to basically accommodate Todd over a specialist blindside flanker. He's a good player, but he's not that good.
If we were going to play two short flankers I'd rather see Jordan Taufua paired with Cane than Todd paired with Cane.
But, I think it will be Ioane, Cane and Whitelock - assuming that Squire isn't available.
I presume most people are thinking that we will name six loose forwards - Cane, Todd, Savea, Fifita, Ioane and Whitelock.
But, if Squire is available - who misses out? Personally, I don't see the point of three openside flankers! For me, it's Ardie.
