Well, you might be right, but no harm in keeping an open mind on positional changes.
If I remember correctly, when Liam Jones was not working out for us as a forward, there were more than a few negative comments for various reasons in trying him down back.
By all means, if we are trialing any of them, let's do it in the VFL first like we did with Jones
That goes for the likes of Kemp as a forward, which I prefer, give him preseason and a block of games in the VFL
