Yes, but he also made most of his differences in the TT. See his giro wins, 2010 TDF it was the TT that made the difference. Most time was gained in 2009 in the TT as well. Even the Vuelta wins in 2012 and 2014, the TT largely made the difference
He made differences in the TT because he was simply a better TT:er, than most of his competitors.
But he was also a better a climber than most of them. You see, he could do both. Those riders usually end up winning races.
If you cant do both at a very high level, then you wont win. Unless you happen to be in the form of your life one time and everything going your way. Like the Hesjedal, Thomas and TGH of the world.
Your argument or the point you was trying to make does not make any sense and throwing Contador into it to try and prove your point is ridiculous.
Remco is a great TT:er right now. He will need to prove his climbing over 3 weeks in longer and tougher mountain stages. Could he gain enough time in the ITTs and "defend" himself well or even be able to climb with the best? The jury is still out on that. There is really no point in tryna say anything more about it.
I think we are lot of people wanting to see it happen. Cycling will be more fun that way with another great rider fighting for the GT wins. We just gonna have to wait and see what the future brings.
