i get that. and you're not wrong.
but the point is, when you can draw walks, hit and run, and steal bases .... then you need fewer doubles and homers to yield the same (relative average) scoring result in an inning.
i think the philosophy and theory still holds. what has changed is that the development of baseball skills has been corrupted, so that these attributes are not well honed or poorly emphasized.
fraser had an M.O., which i heard him speak about, and I also heard jim morris explain the fraser theory one time (i'm paraphrasing a bit, but this is what he/they basically said:
"my 9 athletes, who are faster and more versatile than yours, are going to score one run an inning. and i only need one out of 4 consecutive batters to get a base hit to do it, and a healthy percentage of the time, i can do it with either 3 batters, and no hits, or with only one out of 4 batters needing a base hit. at the end of the game, my one run per inning strategy is pushing double-digit runs."
yes, the long ball and the power game have infected a lot of baseball. but what he preached isn't dead. just that few coaches care to understand and implement it. my point is, di mare of all people should be one of those few.
