For those challenging my point, let me try to make it really simple:
Do you believe Greipel is clean? Yes or no. My post was directed to those who assume he's clean, and that seems to be most of the posters here, who have made this an appreciation thread. If you think he's not clean, then you should be strongly criticizing his statement for hypocrisy. Maybe a few here are doing that, but most are not. (DQ, I think you are saying he is not, in which case you're being consistent in a way the other posters are not. I still think sprinters (road, not track) get less of an advantage from PEDs, but the following argument does not apply to you or anyone who thinks Greipel is juiced).
If Greipel is clean, the next question is, are the sprinters he's competing against clean? Or are at least some of them doping?
If you think at least some of the sprinters are doping, how is a clean Greipel able to beat them? The only answer I see is because the dope they are on does not give them as large an advantage as doping does to GC guys. If it did, a clean sprinter would have no chance, just as we now seem to agree that a clean GC rider has no chance of winning a GT. Granted, that may have changed a little in the past few years, but the evidence is pretty compelling that blood doping to a level the passport can't detect is going to give riders a major advantage.
OTOH, if you think all the sprinters are clean, why? If PEDs can give sprinters as much an advantage as for GC guys, do you really think no one would be taking advantage of that? If Joe Average on PEDs can beat clean Cav, don't you think some rider would be trying that?
Again, let me emphasize I'm not claiming PEDs can't help sprinters at all. I'm simply saying that they don't help them as much as they help guys win GCs. And if Greipel is really clean, I don't see how he could have the success he's had if he was racing doped riders. And this leads me to say that it's easier for him to race clean than it was for Tyler, say, or for Danielson, VDV, and all the others. Not saying it's real easy, a piece of cake, just that the choice a sprinter has to make when confronted with PEDs is not as serious as that for a GC rider. I don't think it's do them or go home. It's more like do them or maybe you won't get quite as good results as you would without them.
Scenery, you make a valid point about Greipel being admirable in potentially subjecting himself to flak from other riders in the peloton. I have no quarrel with that argument. If he really is clean, he deserves some credit for speaking up. But that is a different issue from the one I'm concerned with, how much a sacrifice in potential a sprinter has to make to race clean.
