Like I said, I'd personally vote Clemens into the hall as well, along with Bonds and A-Rod. I just recognize that they're each complicit in their own demise, no matter how many others were using.
The sticking point, unfortunately, is that we just don't know the extent of the use. It could be 75% of players like some have suggested, or it could be a more modest 25%. I'd lean closer to the larger extreme, but we just don't know. So, pretty much all we have to go on is that the guys who DID get caught are guilty. I think that's the perspective that a lot of voters are using.
