Sabermetric methodology usually approaches problems by studying
processes as opposed to studying the sum
results of those processes. Ultimately, this method of study results in the perspective and proportion of the study being disjointed and inaccurate. Studying processes allows the hypothesist to tailor his study to suit his agenda (which, in the sabermetric community, is usually bent on telling the powers-that-be how stupid they are).
For instance, in
Baseball Prospectus’s summary of their philosophy on stolen bases, they tried to show that stolen bases are overrated. To do this, they listed the 20 teams that had stolen the most bases in the last decade and where those team’s offenses ranked within the league....the study’s results were thoroughly inconclusive. They then showed the great offenses and where they ranked in stolen bases....again, the study’s results were very inconclusive. As a general rule, inconclusive results indicate a poorly-done study.
The Baseball Prospectus study did prove one thing....that teams that steal lots of bases cover both ends of the spectrum - a great offense like the 2001 Mariners lead baseball in stolen bases, but so did a bad offense like the 2002 Marlins. The average league rank in runs scored for the teams that stole lots of bases was right along the median. But therein lies the problem....the forementioned inconclusiveness of the study.
That was just a sabermetric-spouting
website that frowned on stolen bases....what do the sabermetric
teams? think of them?
League Rank of Stolen Bases (There is the little caveat that this lists teams by successful stolen base attempts, not total stolen base attempts.)

I think we can all agree that the sabermetric ballclubs, like their ideological counterparts on the internet, think that most often the risk involved in trying to steal a base outweighs the reward.
We now know that teams that steal lots of bases have, on the whole, average offenses. The question now is, whether stealing bases somehow causes an offense to score more runs than it otherwise would have. So the
Baseball Prospectus study should not have been asking “Do teams that steal lots of bases score lots of runs compared to the rest of the league?” No, the study should have instead asked, “Do teams that try to steal lots of bases score more runs than they would have scored if they did not try to steal lots of bases?”
The answer to the latter question is a the same thing that I always hear during one of my conquests of the opposite sex....”Yes, oh God, YES!!!”
I have to admit, this little study of mine is a little bit boring and hard to explain, but if you bear with me I think that you’ll come to the same conclusion (in fact, you won’t be able to come to any other conclusion). The conclusion is that teams that attempt lots of stolen bases - whether those attempts are successful or not - usually score more runs than they would have otherwise scored.
The three teams that led the MLB in stolen bases in each of the past thirty seasons (1974-2003) have offenses that break down like this:
56 of the 90 teams scored
more runs than they otherwise would've scored
25 of the 90 teams scored
fewer runs than they otherwise would've scored
9 of the 90 teams scored
the same number of runs than they would've otherwise scored
Now those are the 90 teams that lead baseball in
successful stolen bases....what about the 90 that led the league in
unsuccessful stolen bases? (Note: There is much overlapping between the two groups.)
45 of the 90 teams scored
more runs than they otherwise would've scored
28 of the 90 teams scored
fewer runs than they otherwise would've scored
17 of the 90 teams scored
the same number of runs than they otherwise would've scored
The reasons that those teams out-perfom their raw numbers are too numerous to cite or to quantify. Here are some of the theories that I have explaining why aggressive teams do so well:
---Fast runners force errors on defenses
---Fast runners foster into the team the value of a base. (I believe that base-stealing teams take pride in always scoring from second on singles and getting to third base on a single.)
---Psychologically, players are more focused on the game when each base seems to matter
The method for determining which teams out-performed, under-performed, or matched what they otherwise would have scored was this: For the three team-SB leaders of each season between 1974 and 2003, I compared their MLB rank of Runs Scored to their MLB rank of OPS. (For the record, the teams that out-performed expectations out-performed them to a much larger degree than the teams that under-performed expectations under-performed.)
Anyway, who gives a shit.
