I'm not sure it's trolling, some players do score more on some teams than others because they get opportunities they wouldn't otherwise, and it's not always about good/bad teams, it's more about depth and role.
Using Bertuzzi as an example, say he is traded to Calgary (simply because I know them best), the Flames already have pretty loaded top powerplay unit, so in Calgary Bertuzzi would be relegated to the second PP unit. This would negatively affect his production. In 2019-20 Bertuzzi had 14 PPP, but that year on Calgary's second PP unit, the top producer was Backlund with 10, second was Lucic with 8, so I don't think it is unreasonable to think he would get 5-6 fewer PPP, that knocks him down to being a 42-43 point player instead of 48.
Now on top of that he would go from being a top line player to let's use 2nd liner for arguments sake, let's assume he scores at the same pace based on ES ice-time, on the Flames Bertuzzi would see probably about 3 minutes less per game at ES (Detroit's top line played more than the Flames top line), just for simpler math I will knock his ES TOI down to 13:45, which is a 35 seconds more than Mangiapane played and that's whose role he'd be filling. Now Bertuzzi would drop from 34 ES points to 30. So now he's potentially down to being a 38-39 point player.
Of course nothing ever works this simply, but it is not really an unfair stance to take.
