BTW - he left Postal bitter and did not speak with Lance for some time. The departure did set his career back a few years by going to a (then) weaker team.
The relevance of both points is as follows: first, if he stayed within the Mennonite faith, he MIGHT have been less likely to use drugs of any type. Second, he was on two teams in the Tour, one of which had a member subsequently dismissed for doping (Tyler Hamilton) and the other which has had a number of people close to a rider allege (yes, not proven) that he took banned peformance enhancers. I don't say that either of these makes Landis guilty; in fact, I would hope the news would have waited until he can get a fair second sample test done in the next couple of days. As with Lance Armstrong, I respect and admire Landis, but I won't if this turns out to be true.
