Yeah, this win definitely rocks. I've not had the privelege of meeting him (though he did come tearing past me on the bike once--that was interesting!), but from everything Ive heard, including several people I ride with who have met him personally, he's a great guy. And like others have said, he's selflessly served for so long, and always seems to just miss the big wins, so this one is even better.
But yeah, I do think he'd need a bit more of the killer instinct to be a real serious contender for the Tour. Maybe Lance can pass some of that off to him...
