my mistake, it is hits, not runs. Don't confuse effective and efficient. In this case the Astros are very efficient, taking advantage of economies of scale. For shifting, effectiveness is what to strive for. A team doesn't want to shift too much because it leaves them vulnerable for a player to "beat the shift" the more a team shifts, the more opportunities to beat the shift, thereby reducing it's effectiveness. Ideally a player would provide subtle fielding position variations to put them in the right fielding position without the coaches/managers calling it. Think more soccer than baseball. Inherently, more is less. Now, I agree 100% not to jump to conclusions with this data. It causes more questions than answers, but progress starts with a question, not an answer.
