David Pinto puts together a chart showing the average age for each team’s offense in 2007 based on plate appearances. Interesting to note the Diamondbacks’ youth, since they didn’t exactly overwhelm anyone this year, but even more interesting to see a difference of more than five years from top to bottom. I would have guessed it would have been less, aside from obvious outliers like the Giants.
It would be interesting to see these numbers calculated for a run of years and then compared to a team’s success over those years. Do teams get better as they get older and then crash? Do young teams inevitably get better? Are successful teams getting younger, as this year’s data seem to suggest? Just wondering.
