BW National League Post View for 2006
If you recall for the last two BW seasons, I have prepared a BW National League Preview. The first year results were surprisingly accurate considering the variables that could affect the results.
I used the following formulas:
For Expected Runs scored:
I used each hitter’s At Bats X OB X Slugging to arrive at expected runs. I summed each teams hitting roster, and prorated it based upon 5640 At Bats (the average number of At Bats per team on my replay runs).
For Expected Runs Yielded:
I used each pitcher’s Innings X ERA to arrive at earned runs for each pitcher. This was summed for all pitchers on the team’s roster and then prorated for 1450 innings (the average number of Innings per team on my replay runs).
I then added a flat 72 runs per team for unearned runs since I did not consider each team’s defense in this review, although that may be a nice improvement.
Based upon the expected runs scored/runs yielded table I estimated the expected wins and losses using the Bill James Pythagorean formula. Here is the expected wins table for the Aaron Division:

It appears that my predictions were not too accurate for
2006 season especially for the Aaron Division and for my team Virginia, Port
Richey, and for Annadale. However, the standings were pretty close in
the Mays Division. Mansfield and Northwoods predictions were right on. Got Daniel’s
I have a couple of ideas to refine this for next season by making sure that the Total Wins = Total Losses.
Overall, it was a fun experience and a great BW season!
Thanks
