I understand what you are saying. I have a program to do the same. The program I use calls that type of analysis "Value Above Mean" - maybe you use the same program.
That is a great way to analyze a scoring system, but it has one major flaw in that the answers will not work if the scoring system is not equitable for each position. If a great pitcher outscores the average pitcher by scoring 300 points versus 150 points, the VAM is going to be very large. However, if a batter scores 550 against an average of 375, his VAM score will not be as good as the pitcher. The fact is, though, that the hitter is actually gaining more points for you than the pitcher is in every respect.
When I did a VAM analysis on this league before I joined, I actually had many pitchers atop the chart. However, practical experience shows that those pitchers are not having the same impact on the game as average hitters are having. I see now that the reason for this is that the scoring system punishes average pitchers so greatly that a great pitcher really stands heads-and-shoulders above the average pitchers - but he still doesn't do nearly as good as a great hitter. Therein lies the flaw that I believe exists.
