Porthen's match data across 21 appearances tells a clear story: he is brought on to defend, averaging just under six tackles per game with a single-game peak of 13. His carry numbers are modest by design, suggesting a role built around physicality and pressure rather than ball-in-hand involvement. When needed, he can contribute with ball in hand, but it is his defensive consistency that defines his impact as a replacement.
