Of the average 15-25 y/o baseball fans, which pre-1980 players would they remember as great? Which pre-1950? Babe Ruth and Jackie Robinson seem obvious. I think Mantle, Mays, and Aaron would be automatic, but...
There are the few stat and history freaks in every generation who can wax eloquently on Arky Vaughn or Ralph Kiner. I'm not talking about them, but the guys you might just run into and talk baseball. Do they think Tim McCarver was one of the greats (he wasn't - he was medium-great) because he's an announcer now? Do they keep some regional memory of the local greats because of their fathers and grandfathers? Can they pull Ty Cobb's name out unaided, or just recognise it? Are there movies in the generational consciousness that preserve (or inflate) some older star's reputation?
Michael and Ben may be my best authorities, but perhaps not. They might tend to know the 15-25 y/o's who know much more than the average, skewing the results.
If someone knows of a good baseball bulletin board where I can post this question, I'd be grateful.
