I figured I wanted to look at whose production increased the most in 1991 and beyond, the first year steroids were "banned" from MLB. In my code, I looked at players who played both from 1985-1990 (a good 6 season sample size) and then looking at any of any of those players who played in 1991 and/or beyond. I cut the PA size off to 1000 PA on both 1985-1990 and 1991-2006. I understand that the years I picked- 1985, 1991, and 2006 are all very arbitrary, but I figured that was my best estimate of baseball when steroid use was at a relative low, when steroid use became rampant, and when steroid use tapered off. I could be totally wrong in my estimates, but I took my best guess.
I then looked at the players' median WAR and wRC+ before and after '91, and then calculated which players had the largest positive difference. Here's my code in case anyone is following along at home.
Here's the top 43 players with the biggest differences in their median wRC+'s before and after '91
And lastly, here are all the player's whose median WAR changed by 1 win or more in '91 or later
What do you guys think of these lists? Again, not a very in-depth analysis, and there are lots of confounding factors and other dilemmas, but it's worth mentioning that 3 of the first 5 players in the wRC+ department all have been connected to steroids, as have 4 of the first 10 in the median WAR change (including Daulton). So what do we think- are Robin Ventura, Kevin Mitchell, and Griffey guilty of juicing?
