I think Langford has been doing well at VFL level. Come 2018, he will get more opportunities at AFL level, and I would not be surprised if he is initially bullied off the ball or something. But that is just another step in learning what is required at the elite level. Intensity CAN be developed. If a player has a desire to win, but they keep finding themselves on the losing side of the contest, they will eventually get fed up and fight back.
Anyway…I sure hope Langford comes on, because I think he is the best prospect we have playing in the VFL.
