A billion times more often than you score a round with no point deduction 9-8 or 9-9, which many people don't seem to grasp.
In theory, the whole point of the 10 point must system is to give the judge the ability to differentiate rounds by a bigger margin when the rounds are one sided. Therefore, if one fighter is beating the other man from pillar to post, a judge has the leeway to score that 10-7 or even 10-2 if it is a severe beating. If there is a knockdown, the judge MUST deduct a point from the fighter who was knocked down. (But, once again, the judge could take off more than one point if he felt the fighter was deeply hurt). Unfortunately, most judges treat the 10 point must system like a 2 point must system, and almost always score the rounds 10-9 if there are no knockdowns. In my opinion, this failure to use the 10 point system properly results in many, many more disputed decisions. It also makes it easier for fights to be fixed.
The first round of Tyson vs Berbick, I think is a good example of a round that should have been scored a 10-8 even though there was no knockdowns.
When the fighter is badly hurt and covering up, with the aid of the ropes to help keep him up and out punched by a wide margin in the round.
Great call, there. Amazing that Thomas never went down. What a chin. Shows what an explosive puncher Tyson was to get Thomas down for the full count.
I think rounds 13 and 14 of the Thrilla in Manila should be scored 10 - 8 even though there aren't any knockdowns.
