"I think my last month of footy's been getting to where I really want to be as a player," Idun told AFL.com.au.
"I had a chat to 'Kingers' (coach Adam Kingsley) a couple of months ago about being a bit more assertive and starting to take more intercept possessions.
"I think I've taken that part of my game to another level. Obviously, there's still a lot of work to go, but I think I'm on the right track, for sure."
