I feel there is always a spot for an experimental spice up as a 17 when it comes to origin because of the fact you tend to have much higher quality forwards who can play bigger minutes than the odd club level team.
But with the HIA rules as they are that would be risky these days, that is why a Player like Capewell is soo valuable in Origin, he covers centre well on both sides of the field and delivers at this level.
I think Hammer has to be in the side as a Winger instead of Coates on the left as well with that view, if we get a fullback injury we can easily cover it with another fullback in very good form.
Adaptability is important, weather we go with Ponga or Walsh at 1 I think we would then have cover for basically every single position on the park, with both of them able to cover 6 or move Hunt there, with Cotter in the team you would also have another Hooker rotation option if you did that.
