When I'm watching a fight, I always try to score rounds to one boxer and not give 10-10's. Admittedly that isn't always possible. I just think :
a. Surely one boxer was better than the other no matter by how little. And
b. The more 10-10 rounds, the more chance of a draw. The more draws, the more re-matches. The more re-matches the less chance of new blood breaking through, eventually leading to stagnation and standards dropping.
It gets to the stage where the more rounds that are scored 10-10 , the more a judge will feel that neither fighters deserved to lose and you'll get artificial draws.
I'll admit it's not ideal, because with the current scoring system, boxer A could shade 4 debatable rounds , another 6 could be scored even and boxer B could dominate 2 rounds doing everything but knock the guy down, and he would be the loser.
I also believe the scoring system is why most people perceive Kovalev as the winner against Ward, while in reality, Kovalev may well have been the aggressor , but you still have to land to win rounds. And Ward pinched rounds. It's about what you prefer, but skill always beats aggression.
