“NHL isn’t a development league” is a convenient excuse we’ve allowed DJ to run out for far too long. It makes no sense. When a young player is ready to compete at this level and has learned what he needs to learn at the AHL level, he needs to play in and keep developing at the NHL level.
Detroit is developing Raymond, Seider, Berggren in the NHL while improving faster than us.
Montreal is developing Caufield, Suzuki, Slafkovsky, Guhle, Harris, Xhekaj in the NHL while playing better than us.
Buffalo is developing Krebs, Power, Peterka, Cozens, Dahlin in the NHL while playing better than us.
We’re currently developing Sanderson, Stutzle, Tkachuk, Batherson, Norris, Pinto, JBD in the NHL. But they aren’t improving as fast as we’d hope.
Even the roster you’re suggesting has Kleven and Thomson developing. It’s just talking point/excuse from a coach who can’t develop defensemen.
