Problem is there is really no way for a bunch of message board devotees to furnish the sort of evidence necessary to prove the existence of "elevated" or "enhanced" performance by illegal substances -- and certainly not just by looking at statistics. Admittedly there are other empirical ways -- drug testing, body measurements, etc. Should there ever be a credible report about Molina or anyone else that substantiates this sort of guilt, then I would have far less difficulty with rampant speculation. A-Rod, IMO has already earned as msny threads here as we see fit.
Short of more substantive reports of this sort, though, all that PED speculation enhances on baseball forums like RZ is a penchant for poor argument and a crazy X-Files herd mentality that assumes "the truth is out there."
