From the always entertaining Wicked Pissa Dude Radio, an attitude and humor filled Boston sports podcast: (www.wickedpissadude.com)
The point I try to emphasize about the steroid thing is that there are all kinds of skew inherent in baseball's numbers.
From 1876-1947 not all the best players were allowed to play.
From 1900-1919 the game was essentially fast pitch softball-spitballs were legal, and the cover practically had to come off before you got a new ball.
From the 1970s on, you have the evolution of the closer and specialized relievers.
From the mid 1990s-to the mid 2000s, you have steroids, but also smaller ballparks, expansion, and a strike zone about the size of a dinner plate.
So all of baseball's numbers, and all of life, really, has to be viewed in the CONTEXT of the game within which they were accomplished.
