But why are there no other close contenders? Don't remember this before really, even in the Armstrong years. Contador, who many on here view as unbeatable, was never as dominant as Froome this tour (so far i'll hasten to add).
Five out of Armstrong's seven wins were by 6 minutes or more. In one of those years, he actually caught Ullrich (considered as a top contender that year) and passed him during a short,flat prologue.
Many think Armstrong could have opened the gap on his rivals by much more, but rode with the leaders through the mountains rather than attacking and opening up gaps. He played it cautiously once the victory seemed assured.
Froome will likely do the same in the Alps. His win is secured if he only stays with the guys who are in the top ten. He doesn't need to attack or open gaps, much like the champion in boxing doesn't need to score a knockout to ratain his belt - just avoid being knocked out.
Froome's major rivals now are a crash, an illness, or a positive doping test. So, I would imagine he is going to take every precaution to avoid those three while sticking close to his rivals for the sake of time.
If that happens and he puts another minute or two into everyone in the next time trial, his winning margin will be comparable to the average winning margin from Armstrong during his seven.
When a rider climbs better than anyone else and places second only to the TT world champion in the TT (by just a few seconds), he can pretty much decide his winning margin on GC.
Opening the gap beyond what it currently is would only serve to raise more suspicious eyebrows on Froome's performance. If you'd like to read up on that in The Clinic, the posts are coming in fast and furious.
