Prime Norris is one of the most gifted offensive fighters I've ever seen, I think he's all wrong for Cotto.
You'd have to favour one of the most beastly 154-pounders ever, and early, possibly by sneer, or Cotto knocks him out with a jab. I would not go with the over.
Miguel Cotto by virtue of his superior athleticism and overwhelming physical tools - faster, more explosive, better combination punching, and punching power. Norris would look stuck in the mud and a few steps behind Merciless Miguel.
This is good.. But not nearly at the level of Hagler probably getting stopped from eating too many straight right hands in his match-up with Floyd "@160".
Yeah Norris will beat the **** out of Cotto. However, what's intriguing is Norri's chin which Cotto can take advantage off.
