"I'm convinced that Jan never won another TDF because he lacked the focus/maturity/discipline to put him over the top of Lance - and that maybe he could have done"
I am one of the believers that Lance Armstrong won for two reasons, he's very good and the team he rode for was the best. I also believe that Armstrong would have finished behind Jan, had they switched teams. I suppose that I am somewhat befuddled by the focus on single team members to the almost total exclusion of the TEAM that won the race.
