Lance is definitely the man, but I would say he's anything but inhuman. This closest of all wins kind of proves that.
And don't forget that, so far, he has only matched the feat already accomplished by Miguel Indurain.
Lance admitted post race that he may have been a bit too confident, but that he will not make that mistake again. I can't wait for next year. At this point, if he wins a sixth, ever, he will be regarded as the best of all time. All that, and a personality, too. (Unlike Indurain.) And an American. (Even better.) A Texan, at that. (In your face, Europe.)
On a different subject: I find it comforting that when Armstrong fell, the field (including Ulrich) waited for him to regain his position. This act of sportsmanship (which reciprocated a similar act by Armstrong the last time he faced Ulrich in the TDF) cost Ulrich seconds, rhythm, and possibly a win (depending on your estimation of Ulrich.) When Lance waited, he was in control. When Ulrich waited, he was desperate to gain it, but he did the right thing. A win based on a fallen yellow jersey would not have been a real win for him. "May the best man win," he said.
I find all the finishers to be world class athletes. For Armstrong to be on top of such a group, five years in a row, seems all the sweeter knowing this.
