Of course but there are many ways to score that don’t involve crossing. We Scored lots of different types of goals last year.Taking it to the extreme, some of the old style managers of the past would say that the more times the ball was in the penalty if area the more chances, and in theory more goals.
I'm not suggesting kick and rush football, but perhaps there is some logic in what Shearer has said. Generally you aren't scoring goals 35 yards plus from the opponents goal.
