Besides an obvious lack of talent on the PP, what I notice most is the poor passing. Watching teams like TB whip it around quickly and accurately is such a stark contrast from the Flyers. Frost, Konecny and Sanheim are skilled enough for a PP1. Tippett, Konecny and Foerster have good shots, but beyond that it's very thin. Tippett doesn't have the vision, while Laughton and Poehling have none of the above. York and Drysdale may get there, but neither has a good point shot. Sure would be nice to still have Gostisbehere at the point. They would still suck, but not as hard.
Now that I think about it, everything about their PP just sucks.
