Here is the article from '03. It has been a constant debate as whether a team benefits more from having a stronger offense, stronger pitching, or a balanced approach. With numbers from 2003', I will attempt to determine the Wins Contributed (WC) by each team based on their Runs Scored for offense per game (RS) and Runs Allowed per game (RA) for pitching, given an average defense. Instead of basing it on actual wins totals for 03', I will use each team's pythagorean record (PR), which bases a team's W-L record based on RS and RA, which is ideal for this study. Method: Hitting: Using a method that is similar to calculate the team's PR and Offensive Winning % (OWP), I have squared RS and divided it by the sum of that team's RS and the RS for the League (LRS) (AL and NL are seperated), this is simply (RS²)/(RS² + LRS²) which will provide the win percentage of that team if that team had average pitching and defense based from their offensive production, I will call this (OWR). For example, if Boston had avg. pitching and defense, their overall winning % would have been 59.8% (.598). Next, we take that .598 and multiply it by 162 to see how many wins Boston would have had with avg. pitching and defense (OWR*162), which will give us 96.09 wins (TOW). Pitching: Following a similar method as mentioned above, except we will use RA and the League Runs Allowed (LRA) the only changes will be that the numerator with will be the LRA instead of the team's RA and the denominator will remain the same (LRA²)/(RA² + LRA²), I will call this (PWP) . This will give us the win percentage of a team with an avg. offense and defense based from their pitching production. To use the Boston example again, if Boston had an avg. offense and defense, their overall winning % would have 48.6% (.486). Like above, we take that .486 and multiply it by 162 to see how many wins Boston would have had with an avg. offense and defense (PWP*162), which would give us .78.86 wins (POW). Combining the two: Now that it has been determined each team's offensive and pitching win totals, we must apply it to the team's PR and then calculate what percentage of those wins were created by the offense and the pitching. This is done by adding up the wins created by the offense and the pitching (TOW+POW) & using the Boston example, it would be 96.09+78.86=174.95. Now that we have the combined win totals, we can now plug one of them to determine the winning % caused by each of them by taking the offensive win total divided by the offensive and pitching totals (TOW/ (TOW+POW)). With Boston, that would determine that the offense was responsible for 55.1% (.551) of the wins and the pitching was responsible for 44.9% (.449) of the wins in 2003'. Now using the pythagorean win total of Boston in 03' of 94 wins, we can take that .551 and multiply it by 94 to show that the Boston offense contributed to 55 wins and Boston's pitching contributed to 39 wins. The final step will be to determine which teams were offensively dominated, pitching dominated, or balanced which will be done by assigning teams with a +.525 Offensive Wins Created % as offensive based, teams with a +.525 Pitching Wins Created % as pitching dominated, and teams within the .475-.525 range as balanced. Then, we will be able to compare which of those groups had the greater success for the 2003' season.

Wins per Team:80.7 Conclusion: There is a small win total variance between teams, but pitching dominated teams had a slightly greater chance of reaching .500. The offensive dominated teams had 4 of the 9 teams above .500, the balanced teams had 6 of the 11 teams above .500, and the pitching dominated teams had 6 of the 10 teams above .500. The balanced teams had a higher Win Total per team, followed by pitching dominated teams, and then by the offense dominated teams. Of the 8 playoff teams, 2 were offensive teams, 3 were balanced, and 3 were pitching dominated. Overall, the balanced teams had the better record per team and have shown the most success in the post-season the past 5 years. Of the last 10 teams to have played in the World Series 9 of them have been balanced, including the last 8. The last team that has played in the World Series that was not balanced was Atlanta in 99'.
