Regarding the '2003 List', I really don't put that much stock into it. It's not the end all-be all that I thought it once was. 1) We don't know what exactly they tested for. 2) We don't know if they took into consideration any of the various Meds one might take at the time. 3) As far as I know, they did NOT test for false-positives. 4) We don't know if the clean players tried to fudge the results to get more testing, as was rumored. 5) What they did test for weren't actually banned at the time of testing. It was a litmus test.
I did and still do somewhat appreciate the 2003 List because it beat the grass to startle the snakes, so to speak. However, I still need more information, and the best way for more information is for a player, any player, to test positive post-2003, and/or have a suspect paper trail, or phone records, or electronic documents,or direct witness testimony (players, family, coaches, trainer, etc), some or all the above.
This isn't the NFL. It is my belief MLB has put forth meaningful testing since first adopted. It may have not put a total end to all of it, but it certainly has landed a serious blow to the PED culture. It's a cat & mouse game now of smarter testing vs smarter drugs, but it's the best it's ever been and that's including every baseball generation before it. Hands down.
As far as fan bias goes... I can only point to Manny Ramirez as going from one of my favorite players of all time to one of my favorite PED users of all time. It had very little to do with the partial 2003 List leak. It had everything to do with what eventually happened years later.
I may well be more forgiving than most. Suspicions are duly noted, but for me, suspicions need to be confirmed. The 2003 List just doesn't automatically confirm it for me. Sorry.
