How about this perspective:
Since 1950, Every Hart winner has had their number retired by a team, except:
Al Rollins: No Hall of Fame, Never played for a team for more than 5 years
Jose Theodore: No cup, No Hall of Fame (also self explanatory)
Lindros: No cup, No Hall of Fame
Fedorov?: Because of contract disputes?
Before 1950, it's definitely a much different era. The majority of early MVPs are actually not retired. Retired numbers only really became a thing in the late 70s. Before it was just seems to be for players who had horrible accidents or died during their careers. When they did start retiring number they are rarely from earlier times. (I think this has to do with the growth of the games popularity around this time, and that mass media (HNIC started 1952) made certain players into heros or icons)
