The training of judges is crucial. Impartiality, objectivity, an ability to concentrate solely on the action, not the attitudes and personas of the participants. I am a true believer that judges should have more seminars on regards to scoring. Ex-world champions are good candidates for these positions since they have the experience in their ring, which other judges do not have. Arguello has done a tremendous job so far.
Punches get one point and knockdowns two points.
Remember, the point of boxing is to hit your opponent. The person with the most hits should win. I think we should bring back the 15 round bout or even go back in time to when the last man standing won the fight. They should be accountable for bad work, like any other job, this will put the pressure on them to be consistent and fair. This is where they should be penalized.
