Based on his reputation, some fishy circumstances around the tests and the strong possibility of mistakes, manipulation, conspiracy (he did win the gold with a Russian taking silver!), etc, I'm giving him the benefit of the doubt.
By the way, I was climbing into Ward (high above Boulder, CO) yesterday afternoon as Tyler passed me heading down the canyon. We exchanged waves - his a big wave and smile. After getting home from the ride, I heard the news. No matter what the truth is, I will always admire him for being a stand-up guy in a sport of prima donnas. I think it's funny that a large number of "serious" roadies couldn't be bothered to lift a hand for a wave and then there's Tyler waving, smiling, talking to folks at the local coffee shop, etc.
I believe him.
