What Walsh obviously means is where is the dodgy Dr now?...Leinders was sent packing early on, doesn't mean his methods aren't still being used but Fuentes and Ferrari were ever present clouds over cycling during that period...at the moment who and where is the boogeyman Dr?...we don't hear that kind of thing any more...you don't have to be a Sky fan to see Walsh's point.
Likewise where are the equivalent Swart, O'Reilly, Betsy type characters coming forward to speak about Froome?...again Walsh has a point, there were always rumours, witnesses etc willing to speak about Lance, not so much with Froome.
As much as the clinic loves to conflate US Postal with Sky there are massive differences, I'm not saying Froome is clean, far from it...but I do think things have moved on in a different direction, cleaner?...no, different drugs we don't yet know about?...that's more plausible for me.
The only people that get pinged for EPO these days are amateurs and second tier pros, the top riders are using something else in my opinion...for what it's worth, and it's only my opinion and carries about as much weight as the hysteria in here about motors...i reckon the top guys are in cahoots with proper doctors and using currently legal cocktails of various meds...see Sharapova and Meldonium although that's now banned...look at Telmisartan, Tramadol etc for what I'm thinking about...also bear in mind peptides that can't currently be tested for and regular compounds like GH and insulin that are still difficult to test for, I reckon that's the method these days...burn the fat off and then use prescription meds for enhanced tissue perfusion, enhanced cardiac function, blocking out the pain etc and you've got the latest 21st century pro cyclist.
