It depends on the type of lack of scoring. Yesterday you had good examples of both types of lack of scoring. In the US-Belgium game it was tense as both teams got chances, especially in the second half when Belgium was getting chance after chance, and it was tense and exciting. But before then was the Argentina-Switzerland game where the lack of scoring mostly seemed to stem from lack of effort, there was nothing tense about it. That’s really what they need to get rid of. America can do low scoring if there’s high chances, you see it in baseball all the time. What they won’t put up with is low effort.
Good points in your post #46.
