Given the way the book has grown over the years, it's way past time they changed the "Positioning, Movement and Teamwork" pages. For a start, what is a "lead AR"? And if, with no obvious authority, a "wide diagonal" is no longer being taught, why is it still in there?
As for the "lazy S", what is the point of that? It assumes you've got time not to run in a straight line! If play is down the middle of the park, why would you want to bend your run away from play toward the "left" touchline? If play ends up on the "right" near the AR, you're nearly the width of the pitch from anywhere near the "lazy S". To me, it's just a bit of the wide diagonal without the flexibility.
