Taking some info from a  Korea Beat  post, True Stories of Korean Baseball has  an interesting  breakdown of how much each team spent per win during 2007.

Samsung(6.2 billion) = 97.3 million per win
Hanhwa (4.6 billion) = 68.3 million per win
Kia (3.5 billion) = 69.75 million per win
Doosan (2.8 billion) = 40.58 million per win
SK (4.02 billion) = 53.2 million per win
Lotte (3.75 billion) = 66.4 million per win
LG (4.085 billion) = 66.97 million per win
Hyundai (4.1 billion) = 73.1 million per win

Wwhat does this tell us? A couple things. One thing is that Samsung  outspends everyone by a fair margin. But I think most people who follow Korean baseball know that already. Doosan got  a good return on its  investment, spending the least  per win. Not bad.  SK, the best team in the KBO last year, was fifth in spending. That ranking will jump to No. 2 for 2008,  which is to be expected  since  the Wyvrens won the league. But as far as I can tell,  the gap has widened.  SK is  arguably better, while I would say  Doosan and Hanwha are worse.  I think Samsung is about the same, or possibly a touch better.

The other thing that jumps out at me is that the Lotte Giants, coming off a  mediocre season, will see a decline in payroll.  Until  Our Heroes rolled into  existence the Giants  have  been the biggest  tightwads 5 or 10 years running. Unfortunately, despite the pomp and circumstance surrounding Jerry Royster’s hiring, it looks like the thriftyness  will continue.      

As Matt from TSOKB points out,  the Woori Heroes are plumetting  toward a payroll  under three  billion. He says that even if the team wins 50 games they’ll still be paying over 40 million won per win. Personally I don’t see them winning 50. I think  they may struggle to win 40. Incidentally the worst team in KBO history was the Binggrae Eagles (now Hanwha), who in  their inaugural season finished 31-76 (.290).
