This morning, someone named AlxFrtz at a baseball blog wrote:

if you got rid of the middle 1/3 of the pitch and got rid of goalies would soccer be as high scoring as basketball?

So a 75 yard by 75 yard field, with 8 yard by 8 feet goals. No goalies. Lets say goals are worth 2, goals from outside of the 18 yard box are worth 3. After goals, the defending team gets the ball back at the goal, basketball style.

What do you think the average score would be if they played for 40 minutes?
