It is not surprising to hear of another doping scandal in the Tour de France. I don’t think that the teams are just being overly cautious to ban all implicated riders, there must be some pretty damming evidence to take such a drastic action. At least they are not covering up the problem as they may have done in the past. It can only be good for the sport which has a bad reputation for doping. They are showing that they are going to be tough on those who break the rules, even though they may be high profile riders.
