Koga is a high-usage operator at full back, averaging over ten carries and more than 75 metres per match across five Championship appearances — numbers that point to a player heavily involved in his side's attacking structure rather than a peripheral presence. His best outing, 18 carries for 106 metres, demonstrates he can sustain that workload at its peak when given the opportunity. His defensive contribution is modest by the numbers, reinforcing that his primary value lies in the carrying and territory-gaining side of the game.
