Depends on what type of inside role you think he will be performing.
The guys you have listed are contested ball animals and in no way is Langford that player. He is a balanced mid and is learning to use his body but he is far more effective with ball in hand. He is creative and that’s what will set him apart.
I think most people expect that we need to have this monster in our midfield but even when you look at Woosha’s midfield at WC you could argue that Cousins, Judd, Kerr and Fletcher were balanced midfielders.
The monsters that people continue to reference are a dying breed and rightfully so. The game is getting faster and with fewer stoppages and players like that have to be extraordinary at what they do to excel.
