They pay homage to the old historical hockey clubs of the past in marketing and incorporating into alternate uniforms, but have their own brand and approach.
For example, the Winter Classic uniforms the Kraken wore as an alternate this season was an homage to the 1917 Seattle Metropolitans that won the Stanley Cup. There's also a Stanley Cup winning banner up in the arena for that season.
They also did an homage last year to the mid-century Seattle Ironmen in their alternate uniform.
But their new branding is so much better than those old teams. Better to start fresh, IMO.
