The issue is that sports science is such a huge area of both research and margin (financial and performance)that it is always one step ahead. I think the knowledge that is available to big teams allows them to dope, Ive always believed they did this using cocktails of TUEs and PEDs at certain times leading up to and through events.
Dont forget that until 2006 taking PEDs in Spain was not illegal – hence tennis, athletes, cyclists and footballers living and ‘working’ there were hugely successful.
BC/SKY has tremendous resource to ensure absolute marginal gains as proven by TUEs through to mahoosive budgets, anything is possible and in cycling probable. You guys saying the history of the sport argument is allowing our prejudices are really, really naive.
It is not just cycling, it is just that cycling takes it more seriously, more fool them? Imagine the other sports that could be dragged to their knees by WADA given the resource.
Joey Deacon sums it up well
Edit: Since 2006, things have improved, mainly because it got harder with the changes in Spain imho
