As much talk as there has been about Contador not being in good form for the first two weeks, it's easy to forget that he attacked on Stage 4, and he was the first GC guy to attack. He's also been the only GC guy to really execute a sudden and powerful attack on a climb for this entire tour. A few other guys have done light-hearted attacks, looked back, and if nobody had countered, they continued on, like Sanchez on his stage win. The only reason Contador has looked like crap is because he didn't drop EVERYBODY immediately, which is what many of us expect out of him.
My point is that, regardless of how he does, he's ridden like a champion, and that's the only reason I like him; it's more fun to watch him race than watch a race that he's not in. I think that mentality is going to run its course over the next couple of days. I think Contador will either win this tour, or lose it by a hefty margin. He leaves it all out on the road, and there's nothing more to do.
