Coach Steve Hansen said Smith's tendency to drift on defence late in games was something the player was trying to fix.
Smith, meanwhile, accepted he could be targeted.
"They might do,'' he said. "The only thing I can do is prepare as well as I can for this game and I'm pretty confidence I can do a good job there and I'm looking forward to the challenge.
"I've just been making sure that defensively I'm making good reads and that sort of thing. It's one area that I've probably worked on in the last few weeks especially because it's a big change up from wing.
"It's just a totally different role. I quite enjoy it, you're a lot more involved defensively. It's just working with the people around you a lot more. On the wing at times [you're only] working with the guy inside you and the last man. I'm pretty confident I can do a good job there.''
