So... basketball has gotten easier to score as people get taller and stronger...
Baseball has gotten harder as pitchers get faster and stronger
Football can adjust the rules to make it a bit easier to score and balance offense and defense
Soccer definitely seems to be getting harder and harder to score as goalies get bigger and stronger
I do think if soccer could make it a bit easier to score that would help a lot of things ... Penalties would be be less definitive to the outcome.
