We need at least a couple of good small or medium defenders over the next two drafts- to replace Rioli and Baker. But, there are some possible options already on the list anyway, Brown, Sonsie, Tresize, Clarke, Banks, Smith, Green and Ralphsmith are already playing those roles or can be repurposed to play them. All of them are looking for a position. Small forwards and NQR mids often make good small defenders. Depending on who we draft, a couple of newbies may start in the backline.
We have enough relatively untried tall defenders to get by for a while. We will probably need someone when we start to climb the ladder. Hawthorn just pulled the trigger on Battle and Barrass. It is easier to find key defenders than key forwards. Blight needs opportunity, Gibcus needs continuity, Even Kosi might need an opportunity to go back before we delist him in two years.
I think the defence is the least of our problems.
