You can set the playoff matchups however you want through NOSE, which is cool.
As far as actual lines with players, I haven't spent any real time working on that. My goal is to create a base ROM that people can use to update for future versions.
The current ROMs I posted have a copy/paste player stats/lines from an early 2018 '94 ROM from @naples39, just for the sake of having differentiation. If I manage to finish this thing before the playoffs, I may spend some time updating for 2018, but that would be some time.
