Chisholm has played at Five eighth and Hooker for France. He also played Wing, Centre, Fullback and halfback for the Storm NSW Cup team and as utility back in the NRL. He's got great ball skills, good speed, great step and a good passing game. His kicking game though is about the same as Moltzen's. He's more of a 6 than a 7 though.
Moltzen is essentially a five-eighth. He's not an organiser, he's someone who runs off good players. His kicking game is non existant, he is not a pressure player. He does know how to run into gaps and read benji's game well and his defence has improved.
Humble looks to be another genuine 6 who can fill in well at fullback.
Miller is the only genuine 7 who can organise a team on the field. He should be the priority signing with Chisholm the back up. Moltzen is currently overpaid and out of position. Humble should also be retained.
