Kennedy (26 y/o) - 49 running metres per game, 15.5 tackles per game at 79% efficiency
Bullemor (21 y/o) - 52 running metres per game, 13.5 tackles per game at 81% efficiency
Flegler (21 y/o) - 74 running metres per game, 21.5 tackles per game at 90% efficiency
Riki (21 y/o) - 72 running metres per game, 31.6 tackles per game at 89% efficiency
It's difficult to split them, because they've all been so average, but based on the numbers you'd say Kennedy has been the most average of the bunch. The eye test backs that up for mine. Tries hard, but certainly not the most talented individual in the world.
