on martin im pretty sure the defensive side of his game has been poor due to the lack of motor.seems to me most times having worked hard for the ball theres little left to defend with.
imo as his tank gets up to standard so will the defensive side of his game.
the area id be working hard on to have him improve is contested possesions the count is just too lobsided.
also imo the two players who should be being groomed at hb are mcintosh and dea. id also like to see what helbig could offer back there.
finally how many sml/med /or tall running defenders do we need. batchelor, dea, deledio, ellis, houli, mcintosh, morris, newman, petterd, vlastuin, and now martin. plus grimes really needs to add some sort of rebounding/running component to his game.
