Seano:
Continued from the previous discussion. I agree that the example you mentioned would/should be considered an effective punch, but I also feel that punches that do damage/power punches should be given given a scoring priority. This is because defensive punching or jabs are generally used as a means to an end (ie. setting up the power shot or preventing your opponent from setting up his own combination), whereas power punches are generally what the fighter is looking to setup.
The same argument can be made for scoring aggression/ring control. It is a secondary scoring criteria due to the fact that the guy moving forward or dictating the pace of the fight might be getting his face punched in as a result. It's hard to justify scoring that with the same weight as damaging your opponent since it only grants you an advantage if it allows you to box effectively.
In Bradley's case, the rounds he won were more the result of Pacquaio taking off too much time in a given round (Pac's negative action) rather than anything he landed (Bradley's positive action). I haven't rewatched it yet, but I can't recall any more than say two rounds where I felt Bradley landed more significant punches than Pacquiao.
