I'm sorry, but I think it is quite hard to "observe" if someone is more or less intellectual without much contact, and
especially when they are speaking a language not your own.
I feel lucky to understand him well enough until the translating guy voiceovers with that medium, B-flat voice, translating Basque Spanish into English with a Russian accent. That always makes everybody sound dimwitted (NOT a Russian comment, besides those guys speak 10 languages). I mean half the cold war was caused by the stupid sounding voiceover guys who made Gorbachev (or our Guy) sound like some idiot with Novacaine and marbles in his mouth.
I think we're all forgetting that Alberto is a kid (sorry if any of you are 26 and take offense, but that's it). He is a kid who has been thrust onto the WORLD stage, and forced to catch more arrows than I ever could at that point in my life.
- One day you're second in the TdF, Chicken's out, Ooop! you're the yellow jersey

- Sorry you can't defend this year, Ooop! because of some dopers from Kazakstan
- Ooop!, Lance wants back in, he's the man!

- Who's the leader? Drum drum drum. Hey did you see only Sparticus beat me? Oooop! Ya, but what'd you think of Lance?
- Twitter, Oooop! You were stupid and missed the crosswind!
- Lance says he's the leader, deserves respect. Who's the leader Alberto?
- Made a mistake, attacked his own team, publicity campaign, Alberto is not a good teammate. Oooop! (again was a mistake, but still) Oh I'm so sorry!
- Look I won the ITT big time. Ooop! Radio Shack! Sound of crickets. Chirp.
- Who's going to win on Mt. Ventoux Alberto? Will you help Lance make the podium? Okey Dokey!

- Lance, fish handshake, Oooop! Danish national anthem! Oooop!
I suggest giving the guy the benefit of the doubt. Besides, he's likely to be around on the top step for some time.
