Has There Been Pessimistic Champion?

[KickMuck]

It comes with the game in boxing where each fighter has an ego. You watch any video nowadays and every boxer is over confident about their ability to win or knock out their opponent. Kell Brook is about GGG and so is Eubank jr, the public may not be as optimistic as the fighters themselves but as a fighter psyching yourself up involves having the belief and confidence to back up you claims and predictions in the ring. We all know that

but

I was just wondering if there has ever been a title holder out there that ever doubted himself against his opponents or over estimated them and come across as the humble "Ive got no chance but i will do my best when we get in the ring" type? And then blow the opponents away. Even if it was a double bluff or anything like that?

I personally cant think of any. Pac springs to mind. I'm sure he was confident but just never crap talked opponents.
