One of the First Mistakes?

I was thinking about this earlier. Is one of the very first mistakes Pac's opponents make still thinking of him as "little Pac." When someone's spent the majority of their career in certain weight classes (the featherweights) the association kinda gets locked in your mind doesn't it? Is that what's happening? Letting the association and familiarity overtake the reality that Pac isn't "little Pac" anymore? I think Pac himself touched on that in one of the post fight interviews where he said he felt bad that everyone kept saying Cotto was stronger and he wanted to prove who the stronger one was.
