What's your measuring point for this? Stats? Well of course pitching was awful if they were facing a bunch of roided up batters! While you may argue that the pitchers were on PEDs as well, I don't believe that those substances help pitchers nearly as much as they help hitters. Pitching is mainly about mechanics and location. PEDs do not help you with either of these. Of course when there is expansion, pitching is going to be thinned out and offense is going to see a boost. I don't know that anyone would argue that. However, in 1976 there were 24 teams and and average of 0.58 HRs per game and in 2000 there were 30 teams and an average of 1.17 HRs per game. There is no way that you can convince me that adding 6 teams would cause the HR rate to more than double. That's an eye popping increase and all you have to do is look at the size and condition of players in the 70s vs the "comic hero" size biceps of the players in the 90's and 00's to get some clue as to what was going on. Also, the HR rate went down one year before steroid testing began in 2006. The news and shame of steroid usage broke well before this. Many players were beginning to realize, before 2006, that the gig was up and the days of just doing whatever you wanted was coming to an end. While they may have not been tested in 2005, they were being watched and scrutinized a lot more closely by the media and the fans. Just as you think some of us are "overblowing" the effect of steroids on baseball, I think you are really overblowing the effect of expansion and the "juiced ball" (especially the juiced ball). While you should expect some increase in offense from expansion, it should not be anywhere near what actually happened.
