Hartigan fits the bill for now in terms of a 2nd key defender behind talia and we may not need another if he comes along nicely. I don't personally want to be using lever as a KPD. He should be our 3rd tall / intercept player and allow Cheney to role over and give the medium talls / utility mids a hard time having an impact forward.
AFL standard backup would be nice to have though. Siggins is probably on the delist heap, who knows how Otten and Shaw will return, we can't bank on them. Ramsey can play back, but looks to be groomed for a forward role, so another back wouldn't go astray.
In terms of forwards, dear has just gone down with another shoulder which is an unfortunate blow. ROB and Lowdens impact as forwards is relatively unproven still, so we may still be okay for now if one of them shows a bit. As I just mentioned though, I could very easily see the club wanting to upgrade on JJ sooner rather than later if we really want to be a genuine threat.
Jake Carlisle would make all of this go away...
