Dragons debutant Tyrell Sloan made a bright start to his NRL career with a performance that featured prominently on the Telstra Tracker leaderboards.

The 19-year-old, who scored a try in a 22-20 win over the Raiders as he capably deputised for the injured Matt Dufty, covered more distance than any other player in round 15 with 9.83 kilometres.

Sloan also ranked fourth for high-speed metres (20km/h or more) with 726m and was the sixth-fastest player of the week (max 35.2km/h).

Dufty is expected to reclaim the No.1 jersey for St George Illawarra's next match against the Warriors, but with the pocket rocket on his way out of the club, Sloan could assume the role full-time in 2022.

Another contender to replace Dufty is Cody Ramsey, who is currently playing on the wing. Ramsey was the king of high-speed distance last round (845m), beating out Manly's Tom Trbojevic (799m).

South Sydney winger Alex Johnston (762m) and Sea Eagles flyer Reuben Garrick (694m) finished either side of Sloan in that category.

Meanwhile, Knights winger Dominic Young announced himself as a premier speedster after he was clocked at 37.4km/h in his team's gritty 10-6 victory over the Warriors on Saturday afternoon.

The Englishman, who made his Super League debut for Huddersfield as a 17-year-old in 2019, became just the fifth player to crack 37km/h this premiership season and is now ranked fourth overall.

Melbourne's Josh Addo-Carr (38.1km/h) is the fastest man of the year but he trailed Young last week, producing a top of 36.9km/h.

Eels lock Nathan Brown did every forward proud as he surprisingly revved up to 35.8km/h to come in fourth for the round.

For relative distance (metres per minute), Penrith's Izaak Tago was first with 113m/m but only played 11 minutes.

Most of the top five received similarly limited game-time but fourth-placed Panthers interchange hooker Mitch Kenny (105m/m) impressively sustained his effort during 33 minutes.
