The sport is cleaning up. Preparation was never discussed years ago, but everyone inside knew things, and just got on with it, because there was nowhere to go with anything without proof. And no-one would have corroborated the allegations, so anyone making them would simply have to leave the sport, which gave them a modest living. A moral problem? Of course, but when you have a mortgage to pay and a family to feed, unless you are certain of a new start, what would you do? It's a brave man that risks his loved ones for a moral point, and plenty probably wished they could, but being blacklisted (and NOT just in the sport) is not funny.
The Hamilton book is a cash in, in my view (with which you might disagree), he has history of storytelling and pathetic excuses when caught (the phantom twin!), and I see him a little like Kimmage, now very bitter and seeking a bit of revenge, at the same time making a profit.
Now, who is the moral one? Not TH or LA, that's for sure. Willy Voet (who did time for his sins), far more credible, nothing left to lose, so spill the facts.
The environment today, according to people I know, is far, far cleaner than it ever was, and just witness how riders finish knackered instead of looking fresh, and times on the big climbs have slowed, as have wattage outputs according to the stats.
That said, Bertie rode everyone off his wheel yesterday, which means either:
Everyone is clean and very tired from a long season, but Bertie is fresh.
Bertis has been at the Spanish steak again.
I think the former is more likely (and sincerely hope so).
