That right there is a graph comparing the average wins per season from 2001 - 2007 (y axis) and Forbes' cost/wins metric that they normalized the same way OPS+ is (x axis), except every playoff victory is worth twice a normal win. The article they posted before I left for LA about the total value of the 30 MLB clubs had the latter listed for each team going back to '00, iirc, so I c/p'd and excel'd and now we have this.
You're seeing, basically, how good each team has been over the course of those seven seasons and how much it cost them to be that good. If I had photoshop on this computer, I would have added two dotted lines. One going vertically from 100 and one going horizontally from 81. These of course would represent the average. Why 2001 to 2007? That's the extent of KW's reign. Since we always seem to be wondering about Kenny's legacy and his skill, this seems as good a way as any to address that on the macro level.
He comes off looking pretty good and, barring the utterly abhorrent '07 (assign blame as you will), he'd be doing even better. Kenny won't ever be declared a genius, but I think this graph indicates he's good at what he does.
**EDIT**
What exactly the X Axis is has caused some confusion. According to Forbes, the efficiency measure:
Compares the number of wins per player payroll relative to the rest of the MLB. Postseason wins count twice as much as regular season wins. A score of 120 means that the team achieved 20% more victories per dollar of payroll compared with the league average.
100 is average, >100 is above average, <100 is below. Sorry about lack of clarity, but I threw this up quickly just because it'd been sitting on this computer for 2 weeks. Should've forwarded it to myself. I humbly beg forgiveness and note that I'm pretty new at this okay? Okay.
