I'm one of your biggest supporters, if you don't know and of the same generation, as I think you know.
So, I am a tad amazed about question one. Pro footballers should all be two footed, other wise your soon sussed and half your game is gone.
Question two. Once over the white line its a football pitch and your in your element. Know the geography of it if not the topography. I, like you I'm sure, have played on pitches where a sat nav would have been useful forgetting around, couldn't see one wing from the other or could only see the crossbar of the opposing goal.
Think it's just a supporters thing. When you play you can influence matters, when you don't you look for things like this as a substitute for not being able to influence.
I prefer blades to kick Lane end first.
Personal observation HBT, no criticism. UTB.
