Or the team could be weaker and they would need to go 1 on 1 in the last section. Then we would know for sure.
P.S. Froome is a great rider, has win a lot, hopefully will win a few more, but i must give Contador one notch more. As if i don't do that, Contador would likely stand up, out of the saddle, and would start brutally proving me wrong. BUT, when determining such things, all don't have to agree. Obviously, if you are a big fan of one or another, that one will likely be rated higher, by you. Nothing wrong with that.
The thing that impressed me about Contador wasn't the attacking which his fans loved but his defending. He's the best defensive rider I've seen in 35 years of watching this sport. Once he got the lead in a race it didn't lose it. And a series of riders found him at times impossible to shake off their wheel. Think Rasmussen in 07, Schleck in several years and Froome in 2014 (Dauphine and Vuelta).
It's a skill he used to turn Schleck's teams to his advantage. Saxo would get rid of the other contenders for him and then he'd stick to Schleck and beat him in the TT. It's not a tactic that worked against Sky except in 2014 when he had beaten Froome in the TT.
A lot of sports fans greatly undervalue defensive work, while overpraising attack. But not me (I was a goalkeeper in another sport)
