The fatal flaw in all the analysis, is the results are based on luck not skill. Once they assume an AB is a random event, then you can assume for the purpose of analysis, all ABs are the same. Why is OPS better than RBI - because we can see that some hitters get more RBI chances than others, and we make the assumptions that quality of pitchers faced and type of ABs even out over a season
ABs are not all the same. In a clutch AB at the end of a game, a hitter will face a different pitcher than in a blow out and be pitched differently. Because baseball is made of 9 three out innings, there are a huge amount of different situations that come up, which lead to the pitcher pitching differently and/or a different pitcher in the game.
If instead of games, each team was given 4374 outs to see how many runs they scored, only 3 things would matter OBP, double plays, and runners left on base at the end of the year. Slg and speed would only matter to the extent that they helped avoid DPs. By taking the entire seasons worth of ABs and treating them the same, you are essentially smoothing out the baseball effect (impact of 9, 3 out inning games on the results). By considering runs scored in blow outs (which skews the data, because by definition, there are a lot of them) the same as game winning runs you minimize the effect of little things (what makes baseball, baseball) on wins.
When we watch a game, we see the actual situation. Statistics don't. That is why watching the game, we see things such as clutch, speed, productive outs.

That was damn good, Sipes. I disagree that the idea of a "stat-based look at baseball" is based around the concept of luck. I think it's the opposite.
But everything else you said really made sense. Good post.

There's nothing better than to realize that the good things about youth don't end with youth itself. It's a matter of realizing that life can be renewed every day you get out of bed without baggage. It's tough to get there, but it's better than the dark thoughts. -Lance
