Brandon Rios - I don't believe the hype

It's clear that Brandon Rios is much bigger than a lightweight. While he's been draining himself quite hard, the size and strength advantage he has is huge compared to his opponents. Lightweight punches don't faze him, and his own punches are real hurtful at that weight. Rios simply walks through the other guys punches, and stops them sooner or later. No doubt Top Rank have played him well in the lightweight division where he has no real competition unlike the 140 division where a few would beat him. But when he steps up to someone his own size, and with real boxing ability, I think he will be exposed for his lack of boxing skills. As someone put it on these forums (in reference to Mosley-Margarito), a guy with no defence will always get knocked out at one point or another. Don't get me wrong, Rios is real exciting simply because of the nature of his style but, his wins seem kind of artificial to me. What do you think?
