Greenies are a completely different level of enhancement... all they do is let you be more of who you already are... they don't change who you are... they don't let you do things you couldn't do without them... greenies would not have made Jay Gibbons look like he belonged...
The 2 things are the same only in an abstract argument and nowhere else...
But we've been thru this already several times...
Maybe they are a different level of enhancement, but they are still artificial enhancements.
And even if all they aide is energy and recovery, that's super significant. Baseball is a grind, guys who can avoid wearing down, or continue playing well as they wind down, are better than those who cannot. If someone who sucks once they tire out is taking illegal amphetamines to avoid tiring out, that's performance enhancement.
If steroid users are eliminated for using steroids, amphetamine users should also be ineligible for using amphetamines. I think distinguishing between the two is hypocritical.
It will be interesting to see what happens with the voting if any clear HOF player in the near future was suspended for amphetamines - and only amphetamines - with no other stink on them. My guess is they are treated just the same as if they had been caught using steroids and HGH, and they should be.
