I got tired of listening to Schlecklet talk early in the Tour when he belittled pretty much everyone. I wouldn't trust his opinion for a movie review.
On the three grand tour thing: none of us, including Contador, know how good he might be. He's got a Giro, a Vuelta, and three TdF's at a younger age than Armstrong was when he won his first Tour and no one could have predicted what was coming.
I expect Alberto told his "dream" to Riis expecting it would stay in confidence, not be used for promotion. In the follow-up, Alberto said it would take time, a change of schedule, etc. to have any chance.
But the guy is 27, he has talent, he's overcome a lot, and it makes perfect sense for him to want to do more in the future than he has in the past. Win the Tour, been there, done that, got lots of yellow T-shirts. Two grand tours in one year? Ticked off on the Bucket List.
So what would be a good answer for the "where do you see yourself in five years?" If he thinks that in four or five years he could get strong enough to make the attempt. I think the progression will be pretty fun to watch. If he could pull off the Tour/whatever double in the next couple of years, I think this conversation might change to the point where a lot of people would like to see him try.
I've said in another thread that horse owners don't announce they're going for the Triple Crown - they try like Hell to win the Kentucky Derby. Tennis players don't say they're trying for the Grand Slam, they fight to win the Australian Open.
If Contador did want to go for this, the last thing he would do is announce it in advance. Heck, Nibali won't say how well he hopes to do at the Vuelta because he doesn't want to jinx it. If Alberto did announce ahead of time, he could get a win and two seconds and some people would say he failed.
The way to do it is to adjust his early schedule so he's fresh for the Giro, and not announce any races beyond. If he wins, he sees how the recovery goes and decides which other grand tour to do. If he rides the Tour, and wins it, he's either got two thirds of it figured out for the next year, or he takes his shot.
Personally I'd rather having him look at his future in those terms than ride the exact same races every year and not test himself.
