Copied from part of a post I made last week:
In his career, Glavine made 682 starts, pitched 4413.1 innings, and had a 3.54 ERA, a 118 ERA+ with 2607 Ks (5.3 K/9) and a 1.31 WHIP
Blyleven made 685 starts, pitched 4970 innings, and had a 3.31 ERA, a 118 ERA+ with 3701 Ks (6.7 K/9) and a 1.20 WHIP
It has nothing to do with compiling. Blyleven was a good pitcher. It's just absurd that the same people that thought Glavine was a lock HOFer thought Blyleven was a joke. The difference between Glavine and Blyleven, aside from the fact that Blyleven pitched deeper into games and struck out a lot more hitters, was that Glavine pitched on better teams. You don't need any particularly advanced stats to see that if you ignore W/L record, Blyleven has the edge in this comparison. I'm not of the opinion that the teams you played on should be the defining factor determining your HOF-worthiness.
