The outside backs have grown more and more important in recent years at both ends of the park.
Gone are the days where wingers in the NRL were simply there to finish plays, and long gone are the days when centres were seen as expendable.
Instead, wingers are required to run the ball, get sets off to a good start, break tackles and be able to pass while having incredible finishing ability.
Centres are also more important than ever, particularly in defence.
Here is every club's centres and wingers ranked.
3. Sydney Roosters
Wingers: Mark Nawaqanitawase and Daniel Tupou
Centres: Billy Smith and Robert Toia
Other options: Junior Pauga, Cody Ramsey, Tommy Talau, Junior Tupou
The Roosters come into the new year expecting their best five to be among the best in the NRL.
Mark Nawaqanitawase has a scarcely believable first season in the competition, taking out the Ken Irvine Medal. He will likely go to another level this year as he continues to learn the game.
Daniel Tupou is one of the best wingers of their generation. Alex Johnston will get the credit as the best, but it's probably not quite right given how well rounded Tupou, who is heading into the final year of his contract and potentially career, is.
Billy Smith's injury issues have cost him a chance to be a representative player to this stage of his career, but he has all the potential, while maybe the only question around Robert Toia is whether he can avoid second-year syndrome.
