I'm pretty sure we don't anchor the defence around someone sat on the bench for 80 minutes most weeks, most of the donkey work has been done by the time he gets on, he's just an inoffensive bit part player who has had little opportunity and done little with it.
If you looked up bang average in the dictionary of football there'd be a picture of John Lundstram this season, the most remarkable thing about him is just how unremarkable he is. He might do something worth praise like this when he gets more of a chance. Right now, he just contributes when needed, which isn't often.
