Lance was a great "responder" to drug therapy but not a great natural talent on the bike. "Der Kaiser" Ullrich was more naturally proficient, he along with about 25 riders were caught in 2006 with bags of their red blood cells stored up and ready to infuse, along with drugs like IGF-1!
but really the evidence would not be good for the UCI (Cycling's governing body) if it were to come out (taking bribes from large teams). It will be interesting if Lance allows Johan Bruyneel's case to go to arbitration, if it does the evidence becomes public! He must not want that.... It would be more like "we might as well loose". Bruyneel wrote a book called we might as well win.
