I think people are blowing the HBO thing out of proportion. Look at it this way, Cotto was favored to win, so in a round-a-bout way, Cotto losing is a bigger story than Margarito winning. When Tyson lost to Buster Douglas, people were more fascinated with seeing replays of him on the canvas struggling to get his mouthpiece in rather than seeing Douglas with his hands raised like Rocky. Even though it's rare to have a fight as great as this take place, it's much more rare to see an undefeated champion get beaten into submission. HBO was playing to what intrigued people more.
