Am I the only one surprised by how much Wiggins has improved compared to 2 years ago - or even 3, when he came 4th in the Tour? This year, he is a TT talent AND a climber. He's sticking with Cadel on the climbs *and* beating Cancellara on a TT.
2 years ago, he was a mid-pack talent. He never was an elite TTer but a second-tier TTer (think Zabriskie or Levi, not Cancellara or Martins) nor was he able to hang with any of the big dogs on the climbs. Nothing in his palmares to date indicates that he'd be able to compete at this level, as opposed to being yet another Gesink or Menchov.
His best stage race so far: 4th in the 2009 TdF. He came in at the same time as Sastre and Frank Schleck on stage 15, 3' behind Nibali and 1'06" behind Contador. On Stage 17, he lost almost a minute to Nibali and 3' to Contador and Frank Schleck. And then he lost 40" to Cancellara on the TT the day after. All of that points to a good rider but not an *elite* rider. Hell, he couldn't beat Froome and Cobo (who? exactly) in the Vuelta last year.
It isn't as if he is a young rider who has gotten stronger as he's matured, either.
