I almost completely agree with this, but I also wouldn't be surprised if there are some struggles early with so much new personnel.
My expectation is that the PP is top 10 over the last 50 games of the season. So long as it is performing like a top 10 unit those final 50 games, I'll be content if the PP starts slow and causes us to finish outside the top 10. However, anything less than that is a complete and total failure in my eyes. We have too many good offensive players with a history of PP success this year. We have to pick 10 guys out of Schenn, Schwartz, Tarasenko, ROR, Bozak, Perron, Steen, Maroon, Fabbri, Petro, Dunn, Parayko and potentially Thomas/Kyrou to form 2 units. There is too much talent and variety in playstyles in that group to blame a middling PP on lack of execution. We can overload one unit with a huge amount of talent, spread talent through both units and mix/match guys based on chemistry/playstyle. We have quick players in that group, big players, good shooters, good passers and a mix of RHS and LHS at each position. If some combination of that group can't be a top 10 PP in the NHL, then the issue is the system.
