Few can find the try line quite like Melbourne's pace aces Suliasi Vunivalu and Josh Addo-Carr, who combined for 42 four-pointers as the Storm swept to premiership honours last year.

But for all their attacking prowess, opposition teams did find fruit when targeting the two wingers as well.

In a watertight Storm defence that conceded just 57 tries for the year, NRL.com stats found Addo-Carr and Vunivalu were responsible for over half of them, registering an unflattering 31 try causes between them.

All's fair in love and try causes, with a fumbled bomb that leads directly to an opposition try counted the same as a four-pointer in the corner thanks to a defensive breakdown further in-field.

So some of Addo-Carr's 16 costly misreads, and Vunivalu's own tally of 15, should be taken with a grain of salt.

But considering they lined up inside Will Chambers and Curtis Scott – who NRL.com found to be the game's best defensive centre pairing in 2017 – and on the end of the tightest defence in the league, it's food for thought.

Ahead of the Storm speedsters in this unflattering statistic among NRL wingers sit Wests Tigers' David Nofoaluma (26 try causes), the Dragons Nene MacDonald (22), Newcastle's Ken Sio (21) and the Warriors' Ken Maumalo (18).

Addo-Carr sits fifth, while Vunivalu ranks equal sixth along with Semi Radradra, Akuila Uate.

Which should see Melbourne's flyers come under the microscope once more in 2018 as oppositions try most anything to unravel the game's premier defence.
