Stat Attack: Indefatigable Cleary won't stop moving

Nathan Cleary has a claim on being the NRL's hardest-working halfback with the Panthers ace constantly covering the most distance in a round.

That was again the case in the preliminary finals as Cleary (9.54km) comfortably finished ahead of Storm five-eighth Cameron Munster (9.39km) and Penrith hooker Api Koroisau (9.19km).

Cleary also ranked equal third for relative distance, averaging 96.9 metres per minute in the gritty 10-6 win over Melbourne on Saturday.

Telstra Tracker data suggests that Cleary's continued dominance in these areas could be attributed to playing on both sides of the field in attack and the Panthers' up-tempo style.

His halves partner Jarome Luai is usually also prominent on the weekly leaderboards for distance covered and intensity, but a stint off the park for a HIA against the Storm bumped him down the lists.

Rabbitohs playmaker Cody Walker (8.36km) ranked 18th for distance while Adam Reynolds, who battled a groin injury against Manly and went off early, didn't crack the top 25.

Elsewhere, Melbourne winger Josh Addo-Carr topped the speed category in his final match for the club, reaching a high of 34.6km/h.

The Bulldogs-bound star outpaced Sea Eagles fullback Tom Trbojevic (34.5km/h) as well as Rabbitohs flyer Jaxson Paulo (34km/h).

Manly flanker Reuben Garrick notched the most high-speed metres (20km/h or more) with 718hsm followed by South Sydney counterparts Alex Johnston (687hsm) and 21-year-old Paulo (684hsm).

Sea Eagles prop Sean Keppie topped the relative distance leaderboard in unfortunate circumstances, averaging 113.5 metres per minute for the six minutes he played before leaving the field for a HIA which eventually ruled him out of the match.

Panthers forward Scott Sorensen went hard with an average of 98.7 metres per minute in his 35-minute stint off the bench which included an inspirational chase to help cut down Jahrome Hughes.
