While I do think Sailor is more comfortable on the Right(where the 7 plays for us), Sailors kicking game is more on the short kicks, he would have to work alot to build the rest.
I think Sailor would work at Centre tbh, he surprisingly worked well as a meter eater in the last game even with his small body but he is like Mam with that slingshot acceleration from a stand still and great hands for offloads and tap passes.
I think if he stays here he could be used as a 17 utility spine/outside back player, cover for Fullback, Wing, Centre, Halves, Hooker and possibly lock if late game.
I would definitely have him as first choice 6 cover at this point.
If I'm honest though he is far too good to not be playing fullback for an NRL team though, there is several teams out there that would improve right now if he was their fullback(Canberra, Dogs, Dragons, Titans especially).
