Interesting point about Shaw because whilst I think he has usually very good positioning, understanding of cover and general game intelligence I do think he has been sometimes a bit lax in closing down his 1-vs-1s and players who hug the byline.
AWB's style of defending when he gets it right, which is usually 7 or 8 times out of 10, completely shut downs a wide player in their tracks. The issue is in open play where AWB finds himself on the half turn, tracking runs, 1-2-1s etc. The staying on your feet stuff is utter BS imo. You need to be both proactive and reactionary with the ability to back it up. I look at Lindelof and the praise he gets for non engagement is as laughable as Neville's praise of Rooney's midfield 'silent domination' performance.
This will be a very interesting year for AWB. Fully rested summer, not getting a call up from England and playing with a really dynamic and smart wide player in front of him. I think Sancho can bring out the best of him because AWB will finally have someone to interplay with, who will take most of the ball playing attention away and he can 'excel' in simply providing overlapping runs/width and draw defenders outwide i.e something he can do and is decent at.
