I think people do that oblivious thing when they don't want to recognise what really happened. I'm a fan of both guys, I do like Cotto but Shane definately hurt him with that right hand.
I had Mosley winning that fight, but IMO that shakeup wasn't really such a big deal. Cotto was disturbed by it but i wouldn't say "hurt" is the correct word. He didn't look out of it at all.
Nobody walks into a fight virtually indestructible. There are times you are hit with a good chin or body shot, and boxing is all about hiding your hurt, or letting your opponent know that the punch didn't hurt when it did in fact hurt. So what Winky or Pac were hurt, stunned, etc...they are in a fight for Christ's sake...damn! The other guy got arms lol...
