I don't think a rebuild has to be a ten year schedule.. And you don't need 4-5 superstars.
The Flyers are unlikely to land the elite players that powered Chicago, TB.
But Wash, St Louis and Vegas have won 3 of the last 6 Cups, Florida, Montreal, Dallas, Boston, Vegas were the losers.
It is still a team sport. What stands out is how unimportant the PP is by itself, it is the balance of PP and PK that matters.
Nor were these three teams carried by exceptional goalie play.
