Players make mistake's, it is quite a statement on Walker's progression that we have gone from
- 2+ years ago, where he made a brain fart or two every game
to
- arguing about "if" he was responsible for a series of events (with several other players) that led to a unfortunate goal.
He no longer needs his speed to make up for bad positioning (regular flaw in his original game), he's become a much better defender and recently is learning to pick his passes a lot better in final attacking play.
I would argue the only thing I would add to his game is the odd early shot, once he gets to the opposition box, players drop off him to double up, shooting occasionally might make him a little more unpredictable and harder to defend against.
