If you put the standard as Yzerman and Lidstrom and applied it to other teams, you'd have to tear down a lot of numbers. If you put the standard as Osgood for goalies, you'd have to tear down some numbers.
What is significant?
You have to go back to 1973-74 season to find a player other than Yzerman, Lidstrom, or Sergei Fedorov who has played more than a decade in Detroit, started his career in Detroit, and was a key player and top player for as long as Osgood was. The player in 1973-74? Alex Delvecchio. Before that, it's 1971 and Gordie Howe.
Norm Ullman in 1968 is deserving, and should have a banner - especially since his number is already retired anyway. But that probably won't happen.
Osgood is definitely a Hall of Fame goalie. A 400-game winner with six 30-win seasons, two Cups, three finals appearances, one of the best winning percentages of all-time, and his only losing season was his second-to-last year, when he was fighting injuries the whole season on a team with the second-most man-games lost to injury that season.
There is a major difference between the unofficial retirements of Fischer, Aurie, and Konstantinov's numbers. Fischer and Konstantinov only played here a few years. Konstantinov may have deserved retirement had he not had his accident. Fischer likely not, although he was very good and on the verge of becoming an elite defenseman. Aurie's number was retired by the club, but no banner was ever hung and it now is not considered retired; it is simply not available for use. Osgood's contributions to the team were greater than any of those three.
At which point, naturally, comes the Shanahan argument. Why shouldn't Shanahan's number be retired? Shanahan wasn't as important as Yzerman or Fedorov, for one. He also didn't begin his career as a Red Wing, which does seem to have an effect on consideration. Finally, would you consider the third-best forward or the starting goaltender more important to a team, whether that team be good or bad? I vote goalie. Very few dominant teams in history, if any, have been so with a bunch of star forwards, one or two good defensemen, and a mediocre goalie. Edmonton is the closest example I can think of, and both Fuhr and Moog were among the better goalies in the league. The team was so stacked they could have kept Gretzky, and started trading some of the less important assets around him for cash, picks, and inferior players. Why not trade Messier and Fuhr instead of Gretzky?
Retire #30.
Osgood's personal achievements are light. That's the knock against him in the HHOF and retiring his number. He has an impressive resume, but he was never really a star in this league. He was never really considered among the top of his position.
I really don't get your line of reasoning. It's as if you're trying to prove Ozzy's number should be retired by naming people who shouldn't have theirs retired. And what does trading Messier or Fuhr have to do with anything??
You're also putting way too much weight on being a Wing for a long time. Yes that's a factor, because you want to retire a number of a player who is associated first and foremost with that team and considered synonymous with the organization (unlike the Avs retiring Bourque's number), but it requires a lot more than that.
And to be clear, I like Ozzy. I've been a fan over the years and defended him here countless times. But I still don't think he warrants having his number retired.
