Ronnie was quite humble during his winning streak, but he became defensive under the guise of arrogance when his reign was being threatened by Jay and when he subsequently lost the Mr. Olympia in 2006 (and onwards). I think his defensiveness/arrogance was more reactionary than it was a latent personality trait of Ronnie's. He does not strike me as a genuinely arrogant type of person at all. It must have been devastating, both professionally and personally, to fall from grace as he did. Although some of his comments ("one white man's opinion") cannot be justified in my mind, I more or less understand why Ronnie reacted as he did. He is still a great champion in my opinion.
