A question for those who understand the modern game: is there a difference between the 7 and 6? Current tip for Origin halves from Gallen is Hodkinson and Pearce - both play number 7 for their clubs. All the talk about 2016 halves for us is non specific re the 2 roles. Back when Cliffy and Tooves were playing, the roles were completely defined. No longer the case? Interested in how it works now Thanks!
