I have Elliott in the same category as the players you've listed (at least).
I'd like to know why you think Carrigan is better than Elliott (If Elliott was a QLDer he'd be playing Origin like Carrigan is probably going to, I've seen a few people say this as an argument, but there's a lot more better locks from NSW, bigger player pool, etc)? Stats suggest the complete opposite (I know they don't mean everything, but they're still important to an extent).
Also how many of those locks can ball play (important in the current meta)?
I think lock/Elliott is one of our best positions when comparing to other teams across all positions.
