Understatement of a life time. Though the response about his height is about a peculiar addition.
He said he's afraid of letting that many people down, and then responds about the height comment with a 7' 2" maybe to try to give people the impression that he's a tall deep voiced man; which would be much better than what we got. It sounds like he's trying to display this image of someone who is afraid of what people would think, though his stats are above average?! Like an overly humble yet intimidating figure?
It seems disingenuous, i think he liked the anonymity as it would allow for his fans fantasy to take over, and i don't think in this example he tried to be accurate at all. Wonder how many people feel like they've been lied to
