Note, for this ranking i used both VORP and my own slight adjustment in multiple cases (which is why in one case, 2000, 6 of the guys I have listed as top 5, as I felt there was no meaningful difference between two of them, although I forget which off the top of my head). Mussina looks a tiny bit worse as compared to my prior assessment, but according to VORP, he should've won two Cy Youngs - 1992 and 1994. Schilling looks a lot worse this time. Brown looks the same. Smoltz looks slightly worse.
At any rate, this "study" made me appreciate Gibson, Seaver and Palmer more than I had. Below is a table of the players and their Top 5 and Top 10 finishes. Top 10 includes the top 5 finishes as well (sorted by top 10):
