I would guess so, but I don't know how many we've scored (my memory is crap and I haven't seen it in the stats).
As I said in an earlier post, perhaps I should have changed the thread title to reflect that what I am really talking about is headed goals from corners. We are probably getting around 3% overall, based on the general ensuing mêlée when the ball is bouncing around in the box. Rather than scoring directly.
But firing crosses over when we are one of the shortest teams around, and our tall players can't head for toffee, would seem like a dubious strategy to me. I'm all for us mixing it up a bit... or learning how to head the ball. Just imagine if we could lift that 3% to 5 or 6%, and the extra points we might pick up.
