Not going to lie, I really prefer keeping Skinner in the lineup, even if Brown is good to go.
RNH-McDavid-Perry
Kane-Drai-Kap
Frederic-Henrique-Skinner
Podz-Janmark-RV
It's the cup final, and I'd rather take the run them over approach vs. anything else by having one of McDavid, Draisaitl, Skinner, and RV coming over the boards every shift. Mix in the fact they'd also be running Kane and Kap, Fred, Podz, and Perry out every shift, and you have the recipe to keep physical and offensive pressure on them at all times.
Basically it's a lineup that will wear you down shift after shift, and will always have someone on the ice who's capable of taking advantage of a breakdown. Plus each line has as a solid defensive backbone with RNH-McDavid, Drai-Kap, Frederic-Rico, and Podz-Janmark, so I'm not concerned in the least about any of them getting caught out on the ice against any competition.
