Your stull stuck in the Bill James era like many of the guys on this board. Even Bill James has admitted that there are many flaws in his metrics. The Cubs GM, World Series Winning Cubs, philoshpy is a fusion of both analytics and some old school.
Some guys on this board have argued an out is an out. Mileninal Bull s***! A speedy contact hitter that puts the ball and play and does not K at a high rate puts more pressure on the D. Then when he is at 1B puts more pressure in the pitcher, and allows the manager more options. Having this type of hitter come to the plate more frequently and the ability to manufacture a run, ends up paying off. Especially in one run tie games.
But go ahead and put some fat ass station to station guy in the lead off spot because he walks a lot and has a higher OPS etc (weighted stat). Lack of a true lead off hitter is a reason AA went and got Ben Revere for the stretch run. It has contributed in part of the reason our offence has sucked when faced with a half decent pitcher and we have had a poor results in one run games.
