And yet, almost every good/respectable team has a solid top-6 player drafted outside the first round that they developed/spent years with the organization, that is producing like a core player.
Anaheim: Troy Terry
Arizona: do you want to be like Arizona?
Boston: Brad Marchand, Patrice Bergeron
Buffalo: not that they're great, but Victor Olofsson
Calgary: Johnny Gaudreau, Andrew Mangiapane
Carolina: Sebastian Aho
Chicago: Alex Debrincat
Colorado: none*
Columbus: Oliver Bjorkstrand, Boone Jenner
Dallas: Jason Robertson, Roope Hintz
Detroit: Tyler Bertuzzi
Edmonton: none*
Florida: none*
Minnesota: Kirill Kaprizov
Montreal: Brendan Gallagher
Nashville: similar boat as LA. They just traded to LA Viktor Arvidsson. So none
New Jersey: Jesper Bratt
Islanders: none. Their top players are all mid-late firsts or from outside the org.
Rangers: none*
Ottawa: Drake Batherson
Philadelphia: none
Pittsburgh: Jake Guentzel
San Jose: Rudolfs Balcers
Seattle: too early
St Louis: Jordan Kyrou, Ivan Barbashev
Tampa Bay: Alex Killorn, Nikita Kucherov, Anthony Cirelli, Brayden Point, Ondrej Palat
Toronto: none*
Vancouver: Nils Hoglander
Vegas: none, but they're an expansion team still leaning on a large core of players from expansion. I don't know if I want to follow their model/infrastructure
Washington: none*
Winnipeg: Andrew Copp
* these teams all have multiple top-5 or straight up first overall picks they lean on heavily. They are currently the exception, but this leans into top picks who succeed in spite of the organization, meaning these aren't sustainable models long term.
So aside from Arizona, Philadelphia, Nashville, the Islanders, expansion teams, and lottery winners, every team has a player on their roster drafted outside the first round in the past 2 decades producing this year among the top 6 forwards.
