I seriously don't think the whole top 10 missed a test within 45 days of the Tour. That aside, the point is that ASO still has to find a plausible excuse to kick out a rider. They can't simply chuck out someone because the fans are booing. And if they say that they are kicking out Piti because he hasn't confessed in OP, they will really look like fools. It is not a question of whether the rider in question is doping or not - unless they test positive, mere suspicion of doping cannot be used as an excuse to kick out someone in the middle of or near the end of the Tour. An excuse has to be stronger than that.
