in no way defending froome here, but do you actually know any cycling history?
tour winners came almost universally from riders who excelled both at mountain climbing and could dominate a TT...Merckx, Ocana, Hinault, etc... hardly ever did a mountain goat win the tour.
o2 vector doping allowed those generally challenged in one area to now excel in both -- pantani and clentadoppucci could TT and hincapie could climb.
if clentadoppucci's doping remains somewhat limited (as last year) he should never ever win a tour again (never should have in the first place) -- unless they do away with TTs altogether (which they are slowly doing). Imagine if clentadoppucci had to ride the tour in the time of hinault and had to compete in a 78km flat TT (as only one of the several TTs in the Tour), he wouldn't even come up in conversation of potential tour winners, not even close.
however, if he is back on the 2009 juice, all bets are off.
