Best lefty off all time? My vote is Koufax!

You keep hammering this point about Koufax benefitting from pitching in Dodger Stadium for his final 5 years (but you ignore the fact that he was in two of the worst pitcher's parks in MLB history for his first 7 years). I've granted you that point and have mentioned multiple times that it should be accounted for and would definitely adjust his peak year numbers down. However, you continue to overlook or ignore the fact that Warren Spahn played in an even MORE favorable park than Koufax did. Are you aware that County Stadium was the friendliest pitcher's park in MLB history prior to Petco Park opening up in 2004? Per Baseball Reference's Park Factor stats, Warren Spahn threw in the #1 friendliest pitchers' park, not just of his era, but of any era prior to the 2000s, and in what still to this day remains as the 2nd friendliest pitcher's park of all time, just a fraction of a hair behind Petco Park in the mid to late 2000s.

So if you want to start making adjustments for Koufax's park, then you have to make them for Spahn and Randy as well. And given his tenure in County Stadium and other extremely friendly pitchers' parks, there is literally no other pitcher in history whose numbers would take a bigger park factor hit than Warren Spahn. His overall numbers would literally take the largest hit of every single major league pitcher who ever threw from the mound by adjusting for park factors. Don't believe me? Go look it up yourself.

Meanwhile, Randy Johnson pitched in one of the worst pitchers' parks in MLB history when he won his 4 consecutive CYAs in Arizona. I can't even imagine wanting or needing to IMPROVE his numbers from those 4 years, but the data tells us that we should. Pretty insane, if you ask me.

No one is denying Spahn benefited from his park. Like most pitchers, his home numbers are better, and it’s one of the factors holding down his adjusted rate stats, which are still excellent.

Unlike Koufax, his ERA doesn’t double or triple each year outside of Dodger Stadium vs. being at Dodger stadium, as was broken down several times already. Unlike Koufax, he was a star pitcher before he got to County Stadium at age 32, when Koufax had been retired for 2 years.

Your comeback will be to ignore this or to compare their home/road splits on a career level to cover up Sandy’s dodger stadium difference as opposed to his other home parks that don’t have extreme problems and didn’t align perfectly with his only good years.

You’ll get no argument from me that Spahn was better than Johnson, for numerous reasons. The problem is you chose to make the absurd proclamation, supported by 0 prominent and known expert baseball statisticians, that Spahn was “above average, at best”. Not being as good as Randy Johnson after you adjust for park is not a winning argument when this is your hypothesis. It’s shifting the goalpost, very obviously and poorly. A 119 ERA+, adjusted for park, in over 5,000 IP is not “above average at best” according to any prominent baseball statistician or by common sense.

Also, isn’t your argument you just made a few hours ago that Sandy’s first 7 years should be ignored? No home park effect creates Sandy’s terrible first half of his career. Interesting how his first half matters when it helps Sandy and does not matter when it hurts Sandy. Like all the Koufax arguments, it’s an argument from conclusion in which the argument is formulated after the conclusion without any regard for consistency to previous statements.

I dont even know what to do with this. You just get more and more clueless as this thread goes along. You're not even trying to put forth honest arguments anymore. You're just trolling now. I'm done with you. Welcome to my ignore list along with Snow PaTroll. But hey, at least you got one thing right. I'm going to ignore you now.
