I mean, it's kind of a necessary reality for clubs that didn't exist during an era when every team was almost guaranteed to have a HOF'er on their roster.
Number retirements aren't like the Hall of Fame, it's not a best player contest. It's more about telling the story of the franchise. For expansion clubs that's typically going to involve a non-superstar player or two who set the tone for the culture in the first generation of the club's existence -- often, guys who could have been superstars in a more established/contending environment. For O6 teams that's necessarily going to mean first ballot type players, but for expansion clubs it's more like your Mikko Koivu, Rick Nash, Pekka Rinne types.
