Bill, you know as well as I do that todays games is far different then even the late 80's early 90's. So even tho I applaud your effort for finding all those players, they are irrelevant to me, because the game is alot different these day.
So after you thin your list down to players of this error what do you have? Randy Johnson, NL pitcher, faired decently not great in AL East, KB NL pitcher, not so well in ALE. Curt Schilling, He was injured all year when he was 38, so obviously if healthy his stats would look better. Also don't bring up record, W-L is a horrible stat to judge a pitcher by and you know this.
Ok so we got who left? Clemens( do I need to go into this?), Smoltz, Career NL pitcher, Cone I'll give you, even tho his yrs where unspectacular but passable. Moyer and Ryan are abnormalities. Ryan was a physical freak , he still could throw mid 90's at that age. And Moyer, well theres no explaining it, hes just got it done for a long time.
Also, you think Mussina could be a top 6 pitcher in the AL according to your argument at the top of your post? This is just madness and I don't even know where to begin, maybe its me, but does anyone else see this as insanity? Mussina might have a bounce back yr, but he will never be a top 6 pitcher, at this point his own club could start 3 to 4 pitchers in front of him.
