It would be neat to see if someone could compile a stat that shows the records of the teams for both Matty and Walter through out their careers. That could help in closing the debate about the huge gap in lifetime win% that Matty has over Johnson.

Well, this is hardly an exhaustive study, but it does show how good the New York Giants and Washington Senators were overall during the careers of Walter Johnson and Christy Mathewson. Keep in mind that both Mathewson and Johnson, throughout their careers, also appeared in games they did not start. Mathewson pitched in 635 games for the Giants, starting 551. Johnson pitched in 802 games, starting 666. So, when I refer to games that they ultimately factored in the decision (a win or a loss), that decision was not necessarily derrived from a start.
Between 1900 and 1916, the New York Giants went 1,456-1,080, good for a .574 winning percentage during Mathewson's career. Mathewson went 372-188 with the Giants, giving him a .664 winning percentage. In games where Mathewson did not factor in the decision, the Giants were 1,084-892, a .549 winning percentage.
Between 1907 and 1927, the Washington Senators went 1,559-1,609, giving them a .492 winning percentage during Johnson's career. Johnson went 417-279 with the Senators, giving him a .599 winning percentage. In games where Johnson did not factor in the decision, the Senators were 1,142-1,330, a .462 winning percentage.
In games where neither Mathewson or Johnson factored in the decision, the Giants (.549) had a .087 better winning percentage than the Senators (.462). That's 8.7%. Over the course of a 155 game season, that means, on average, the Giants won about 14 (13.5) more games than the Senators. From one perspective, if the Senators had won 8.7% more starts when Walter Johnson played in Washington, Johnson would have won an additional 58 games (666 starts x 0.087 = 57.942).
A few more numbers to bounce around in our brains. I think all of these are accurate, though it's late.
The Giants had a .574 winning percentage in the Mathewson era, compared to a .664 winning percentage for Mathewson himself. Mathewson's personal winning percentage was .090, or 9% better than his team's. Mathewson win-loss record was responsible for a bump of .025, or 2.5% (.574 with Mathewson - .549 without Mathewson) to his team's overall win percentage.
The Senators had a .492 winning percentage in the Johnson era, compared to a .599 winning percentage for Johnson himself. Johnson's personal winning percentage was .107, or 10.7% better, than his team's. Johnson's win-loss record was responsible for a bump of .030, or 3.0% (.492 with Johnson - .462 without Johnson) to his team's overall win percentage.
The hypothesis that Walter Johnson would have won more games had he pitched in New York is a valid one, of course. Trying to accurately forecast just how many more games he might have won, though, is next to impossible. I do feel that Johnson could have been the second pitcher ever to win 500 games though.
Something to think about, anyway.
