I started to compose the remainder of this entry as a comment, but it got long enough that I decided to post it here instead.
I may be an atypical baseball fan; I enjoy watching the game, and I follow what's going on around the leagues and in the standings each year, but I don't really care about the history of the game or about who set or broke what record. But isn't the Hall supposed to be about the history of the game? I mean, if the point is to run down an itemized list -- the record for most curveballs in a single game is held by Joe "Slimy" Tibbles, or the record for the most over-the-shoulder running catches in one season by a second baseman under 5'6", that whole Guinness Book thing -- then sure, set moralistic constraints on the records.
But that's not my impression of what the Hall is supposed to be. Isn't it supposed to ensure that the game isn't lost, that the story of the game isn't forgotten? Isn't it meant to trigger meandering happy retellings of games or seasons, or to inspire the young'uns to go look up the stories behind the numbers? (In which case, all the insufferably smug, self-congratulatory articles about "I did my duty and kept him out!" kind of defeat the whole effort.)
Records aren't bestowed, they're achieved. Sometimes they're earned, sometimes they're "stolen", but they aren't some sacred trust held by the BBWAA, are they? When it comes to grammar I'm a prescriptivist, but I would think that a hall of fame is descriptivist by nature. And everything should be asterisked. Give me the stat, and then give me the context. Admit that the game has never really been pure and that the conditions have never been equal from one season or even one game to another. Tell me which record-setting players were drinking heavily, or snorting cocaine, or taking speed; tell me which players had to contend with racism, or with a short season, or with wool uniforms, or with being snowed out of two consecutive starts; tell me which parks give what advantages and the theories of why; tell me how the numbers changed with the advent of lights (night games), with standardized ball/bat manufacture, with pitching mound changes. You'd think the anti-sabermetrics types particularly would value the story over the raw numbers.
It's a Hall of Fame, not a Hall of Vaunted Moral and Ethical Purity. Five minutes reading about the most celebrated members would illustrate that.
