I think it's a bit of a myth that the likes of Larkey and Mitch Lewis are young. They were drafted in 2016 and Larkey is turning 26 next year. He is right in his prime in the next 3-4 years, then he will be nearly as old as Steven May who most are predicting to fall off a cliff soon. North possibly get a tilt at a flag right at the back end of this period.
I think it just goes to show how long it takes some of these KPF to really find their feet in this league, and is also why JVR did such a great job this season. I feel like he has a great chance to be just as good as these guys at even earlier age.
