Some notes to the data:
- This data covers 1991-2008 (the entire period that they pitched for the Braves). During this time Smoltz was a Brave for all 18 years, Maddux was with the Braves from 1993-2003 and Glavine from 1991-2002.
- Smoltz was the Braves closer for the 2nd half of 2001 through the 2004.
I find all of this quite impressive. Sure, they made a lot more money, but they backed it up. Their ERA was 21% better than the rest of the team, they won 9% more games, clearly had a better ERA year after year, and more than pitched their fair share of innings.
In fact, the most impressive stat to me is that between 1993-1998 the Big 3 threw 50.3% of the total innings for the Braves. Three pitchers throwing that many innings is simply incredible. I can't imagine there are too many, if any, teams in the last 50+ years that could even come close to that.
