Player value correlation is indeed a thing. So too match ups in the next game, player playing out of position, etc. I haven't experimented but you are probably right that a model that could use factors like these effectively would outperform what I described. But they aren't critical to building a model that will beat your mates and land you on the single-digits top%.
