The strongest steroids were in use in the 80's and early 90's long before scoring and home runs climbed. As has been said, there are better reasons for the power binge than steroids. Once you look a little deeper it becomes obvious.
Please provide the stats of which players were using steroids (including percentage of the league) and how in was at it's height in somehow the 80's, 90's, and 2001-2004 all at the same time. As for body size, players are taller now than in the past (mainly due to the focus on taller pitchers over the last decade). That accounts for the larger weight. Yet in the 90's into 2005 players height was very similar to the late 70's and early 80's, but weight increased dramatically by 1995. There is also no account for muscle mass/body fat.
BTW...2000 was the height, but 2001-2004 averaged more home runs per game than 96-99. In fact, you have to take into account Coors installed the humidor in 2002 which directly led to a major drop off in home runs at Coors. So you can inflate 2001-2004 even more. The anomaly was 2000, and it was a 1 year number. Every year was less than 2000. Yet 2001-2004 was higher than 96-99. There was not some major drop off. If you look at the last 4 years, you have to go back to the early 90's to find a 4 year stretch similar. That is a drop off.
You cannot simply take 2000 and say "hey, there was a drop off so it's not steroids." You have to take more than one year and look at standard deviations and averages. Once you do that, 2001-2004 fits right in with the late 90's and 2000. On the other hand, 2009-2012 does not. You also can't just put a stake in the ground and say "this point is where it should stop." It's not like when someone stops using PED's they suddenly deflate, and also in the mean time testing evolves.
