only Pittsburgh can match and even they can't truly match it because Toronto goes 3 deep,
Crosby is the #2C in the entire league - Tavares is top 10.
Malkin is the #3C in the entire league - Matthews is top 15.
Kadri is a great, probably top 20/top 25C, and Brassard is not even a top 50 guy --- but at the end of the day, the Penguins definitely win out in center depth because they still have the better players.
Their wing depth is about similar, their defensive depth is equally as terrible, but their goaltending is also much better.
For reference of center listing (approximately, order could be slightly argued)
McDavid
Crosby
Malkin
Stamkos
Kopitar = Bergeron = Barkov = Backstrom
Tavares = Seguin
Getzlaf

MacK
Scheifele = Matthews = Kuznetsov
Draisaitl = Eichel = Pavelski
Toews (fallen a lot over last few seasons)
