Obviously, I'm a curmudgeonly old get and routinely dismiss anything invented after 1971.
However, I said days ago that I can accept that these things might be useful to coaching staff, but as a consumer of the game I find it doesn't enhance the experience for me at all. I'm no more interested in what people think should happen than I am about having a detailed run-down of players' eating regime or toilet routine.
That's why you always dismiss everything I say....
