I'd say low risk of a Weideman - now there's a static kick-mark player.Yeah Amiss is a good result/comparison.
But for an early pick - How much risk is there he ends up more like Sam Weideman?
Personally, think we should be prioritising getting someone to replace Lynch - i.e. that can play No 1 forward and take down the opposition's best defender. Not sure Armstrong will be that, given he looks to have some physical limitations.
Sims is your Lynch type. Let's get both.
