I noticed something about hitters who played their whole careers (or most of it) in Coors. They all have lifetime OPS in my test league that were 50+ points below their real life career averages. That was the case for Todd Helton, Carlos Gonzalez, Troy Tulowitzki.

Another player that stood out to me was David Ortiz. In my OOTP test league, he never went to the Red Sox. Without playing in Fenway, he ended up with exactly 400 HR in 2456 career games, as opposed to 541 in 2408 games in the real world.

I then ran another historical game, also covering 2000-17. Once again, I had development turned off, 1-year recalc and the ratings were based on real stats.But, this time, I used real historical transactions and real historical lineups. That way, everyone was forced to play in the same home parks as they did in real life, as well as being used in the lineup the same way as they really were. The big hit in career OPS that real life Rockies hitters got went away in that test league. Meanwhile, Ortiz's career HR dropped from his real figure, but only down to a more realistic 518 HR.

This makes me that basing the ratings on "real stats" result in park adjusted figures being used for the ratings. That would appear to account for why Rockies hitters get a big drop in their stats when their career paths take them away from the Rockies (either through trade or free agency), but not have that happen when they stay on the same career path in terms of teams.

Meanwhile, the coaching system was turned off in both test leagues. So, that can be eliminated as a potential variable.

I think the 400 HRs by Ortiz is what you get when you turn the steroids off (writss the bitter Yankees fan).
