I'm not defending the guy, but I'll play Devil's Advocate. I just checked the website, and Hincapie was listed, so if it's current, that's one. Back when I was a naive LA fan, I followed CC on twitter. Except for riding the scooter in Hawaii, he wasn't even on the road with Lance for his comeback - Dean Golich was the man doing tests and things.
But Carmichael does have a business, with a new building built to order, and sixty coaches listed. Running a business like that is pretty much a full time job. He was also coaching some development team in South America or somewhere, and the business does coach Ironman triathletes and athletes in other sports.
I'm not sure why he needs to coach a pro cyclist to justify himself to anyone. How many coaches based in America currently coach riders in the pro peloton? I have no clue. But if a guy with kids builds a successful business where he gets to spend time with them, I don't trash him because he's moved on from what he claimed to do years ago.
