As a broader philosophical point I think it’s better to include finals scores in analysis, it provides extra data.
People can say finals is different to normal footy, but so are showdowns, Derbies, Anzac games, rivalry games, games in the wet, games where your team drastically over or underperforms. It’s still footy and should be taken as evidence of a players performance in a past season.
The only exception would be someone like Dusty who clearly set himself to play finals and cruise in the regular season. Not many players have played like that, maybe Danger will moving forward
