We expect athletes to do whatever it takes to win, so we shouldn't act so surprised when they take us up on the offer. While we retrospectively discredit '90's era baseball, the product was a lot better then than it is today. Instead of barrel-chested comic book heroes crushing 500-foot home runs, we have entire rosters that are created using sabermetrics. You don't need to do a statistical analysis of "batting average on balls in play" when your No. 3 hitter crushes 70 bombs per season, and it's a lot more fun that way.
Baseball was at its best during the "Steroid Era."
