It makes me go "ho! ho! ho!"

PB values are not an accurate predictor of player value.

There is not such estimate.

We use WHIP, RATIO, OPS, slg pct. and lots of other tools to help put a quantitative number on player value - but none of them are accurate, just tools.

We like to argue over which is the better estimate.

But nobody really knows.

For me, PB value puts way too much emphasis on plate appearances and/or IP.

2B Todd Walker 5.634 .656/.799 OPS 647=PA

2B Jeff Kent 5.494 .989/.829 OPS 552=PA

Who would you rather have on your team?
(Kent has better defense.)

But again...it comes down to opinion. To pretend the PB values are with 2.5% of accuracy is interesting, but it isn't math.
