IMO, Markov is the most in danger on that list. There is a number of kids coming through who can do what he does, but likely better. And then you see him behind Stack and McIntosh for a backline spot. That is tough.
I had high hopes for Miller, and the club has kept him round, but needs to do more than just show potential soon.
Nank will be a priority resigning, can’t see him going anywhere next year.
Graham will be kept as well. Can’t see either SA club being in the position to offer him a deal we can’t accomodate if Rance doesn’t come back.
