This is a circular argument. A logical falacy. It's not a valid argument. Dodger Stadium has an average park factor of 95. That means that Koufax benefited 5% from pitching there. 5% is all. The reason he was so good in Dodger Stadium is because he is the best lefty of all time. Dodger Stadium's park factor is in line with other pitchers parks. The Astrodome averaged 94. Candlestick Park averaged 97. Why couldn't Marichal come within 2% of Koufax's home ERA? Or any Astros pitcher match it?
Now let's look at hitters parks. The "Launching Pad" in Atlanta had an average park factor of 105 with a high of 114. So, a hitter in Atlanta got the same bonus that a pitcher did in Dodger Stadium. The Baker Bowl was a little more extreme. From 1921-1937 it averaged 112 with a high of 116. The Rockies average park factor for their entire history...118 with a high of 128. I will let you figure out Fenway, but it is going to be close to 105, the best season was 112. I find it a little hypocritical that you mention Jim Rice. Sure he got a boost from the Green Monster being 310 feet in LF. Why doesn't Koufax get the same respect for pitching 4 seasons with a LF screen 251 feet in LF?
A normal park factor is 100. +/- 5% is a normal range. Denver is way outside of any normal range. That none of the parks in the discussion have had a single season what Denver averages is why home/road spits matter for Rockies players. For Koufax, it is a very minor factor.
