Why player roles matter more than position labels

Two players can share the same jersey number and influence a match in completely different ways. PTN uses dimensions and percentiles to make those differences visible.

Position is only the starting point

Calling two players fullbacks tells us where they usually line up. It does not tell us whether they are primarily ball-runners, creators, support players or yardage workers.

The same problem exists across halves, centres and forwards. A role-aware model needs to compare how players produce value, not just the label printed on the team sheet.

The six PTN dimensions

PTN currently organises player output into six broad dimensions.

  • Playmaking, creation, kicking control and receipt involvement.
  • Evasiveness, line breaks, tackle breaks and open-field running.
  • Workrate, repeated involvement with and without the ball.
  • Finishing, tries and line-breaking output.
  • Carry, run metres, post-contact work, offloads and yardage.
  • Defence, tackle load adjusted for missed tackles.

Why percentiles matter

Raw numbers can mislead when different positions have completely different workloads. PTN first compares a player with positional peers, then converts that comparison into percentiles.

A 90th-percentile Carry score means the player is exceptional for that role. It does not mean a winger and a prop should be expected to produce the same raw metres or carries.

PLAY THE NUMBERSObserved data and PTN-derived analysis are kept separate.

Where PTN uses official NRL statistics, the raw inputs are identified as source data. Ratings, percentiles, model probabilities and interpretation are Play The Numbers calculations.
