Berto's corner was nonexistent

[fan johnny]

IMO Berto's bad habits have finally come back to bite him in the ass, same thing with Lopez, Berto was happy fighting B level fighters and calling out the big names like Mayweather, Mosley, Pacquiao, and Cotto, yet would fight guys like Quintana, Freddy Hernandez, and Juan Urango (who would have been a good win at 140 and if he won like Alexander did), Berto IMO was never that good and too flawed for the big stage, Ortiz knocks him cold in a rematch

Berto didn't listen to his corner. Had he been listening he would have stopped looking for a knockout shot and boxed more, just like they were telling him to do, and got hit less. My guess is that Berto's mistake is he thinks all he has to do is load up and connect and the fight is over.
