I admit I ignored the NPPG in all previous seasons. So I don't honestly know anything about the illustrious legacy of the format. But to me, I don't care about the playoffs after our team is done. So really, I'd just keep it basically the same as the regular season. Give us points based on Preds games only, including play-ins. Once the Preds are done, I'm done.
The playoffs are ran differently than the regular season. You pick 3 F's, 2 D's, 1 G from any of the teams still alive, but you can only pick each player once unless you have picked both goalies in the finals.
