Maybe you guys didn't see the uppercut he landed at the end, but he definitely hits hard. Even his right cross and left hooks were landing hard. I don't think he always tries to land hard, and he threw 300 punches in that fight so obviously he wasn't trying to take the guy out early. He was deadly accurate (52%), his defense has gotten a lot better, and he does have work to do, being as short as he does with as limited mobility as he does he needs to continue to improve a very good jab, and he needs to work the body A LOT more. THe problem with these extremely quick handed guys like him and RJJ is that he can land at will upstairs, but the only reason Cotto finishes half of his opponents is with the bodywork he sets it up with. Once again Berto isn't the hardest puncher in the world, but IMO he hits harder than Cotto at WW, and he hits harder than guys like Pavlik. Only time will tell. For now he needs to work on
1. Keeping his hands up, or work on moving better
2. Going to the body constantly
3. Throw more punches, but always behind the jab.
