So what? Scotland could always take the initiative and try it out. On the face of it, it does seem a fairly sensible suggestion to me. And given where we are just now, we're going to have to start trying some rather leftfield stuff.
To try it out though we require a friendly game for sole purposes of trying things out. And as we all know when it comes to friendlies we either A- don't play them or B- use them as a money making exercise.
