The next two players on the list are, in alphabetical order, Tom Glavine and John Smoltz. It’s hard to rank them, which is odd since we’re talking two pitchers who played for the same team in the same era, but the shape of their contributions is different.
Through 1999, Glavine was clearly far ahead. But since then, Smoltz had a detour to the pen, Glavine left the team, and Smoltz came back for two strong years in the rotation. There’s also the matter of the postseason, which for these two is about an entire season’s worth. Glavine’s postseason results are actually not bad at all: he’s only 14-16, but his ERA is 3.42. But Smoltz’s ERA is 2.65 and his record 15-4. How much weight do we give that? And if it’s a lot, what about Glavine winning a World Series MVP award?
