Was he the 5th best pitcher, though? Looking at 1991-2002: Maddux, Johnson, Clemens and Martinez are clearly superior. The next tier would include Schilling, Brown, Mussina, Glavine, and Smoltz, with maybe Cone probably a half step down from that group. Schilling had a far stronger peak and far more dominant post-season performance. Smoltz had a stronger peak and went 15-4 in the postseason with a 2.67 ERA. In 1000 fewer innings he finished with 400 more strikeouts than Glavine. He had basically the same number of complete games in 200 fewer starts. So I think a very strong case can be made that Glavine was the 3rd best pitcher on his own team and maybe roughly tied for #7 with Mussina.
