Schumacher tests positive for CERA/EPO

Big surprise here. He's never really been considered a great time trialist, and then smokes the current Time Trial World Champ Fabian Cancellara in both time trials and this only causes a "minor sensation" in the race. Doped to the gills, i think. The only surprise is why it took so long to figure out. They caught Ricco days later. Why did this take a few months? Ricco was already "on the radar" after the Giro but shouldn't Schumachers sudden time trialing prowess put him on somebody's radar?
