It's also probably too early in the season to read anything into the results, but I'm going to ponder anyway. As with last year's Vuelta, you get the feeling that Contador's acceleration is fractionally less powerful and sustainable than it used to be. Watching him grind his way onto Nibali's back wheel was a real surprise, Nibali being the sort of diesel climber that an explosive rider like Contador should be able to catch, match or despatch with a couple of pedal turns.
Evans and Froome were equally interesting. Both capable climbers, but falling short of the acceleration and top speed of Rodriguez or Contador, they overcame their shortfalls with brains and, in Froome's case with what I suspect was a bit of bluffing. They stayed within themselves, didn't redline it following attacks they couldn't catch, and used the strength they'd saved to attack when their technically faster rivals were depleted. I'd expect that of a canny rider like Evans, but seeing it from Froome was a surprise.
I wish the camera had been on their faces when he tore past them. If the finish had been half a km further on, I think he might have caught Rodriguez and got the stage win as well as the leader's jersey.
And as for Rodriguez's attack, what can you say? It wasn't his usual lethal turn of speed, but it came when his major rivals were unprepared, and he used the element of surprise to make it stick. Poetic justice, given how Contador used similar tactics to pinch last year's Vuelta out from under J-Rod's nose.
