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.

6. The Dolphins

Wingers: Jack Bostock and Jamayne Isaako
Centres: Herbie Farnworth and Selwyn Cobbo
Other options: Jake Averillo, Tevita Naufahu, LJ Nonu

The Dolphins have one of the better outside back combinations in the competition - that has to be the truth if Jake Averillo is missing out.

Herbie Farnworth may be the game's best centre, while the addition of Selwyn Cobbo, if he is at his best, will add plenty.

Jack Bostock, who misses the opening two months of the season, is a towering presence on the wing, and Jamayne Isaako has been the club's most consistent player since he joined in their foundation season.
