A round can't be scored a draw it should be 10/9 regardless but if it's too close some choose the aggression & activity but technically it should be on the champ... Pac vs JMM 1 & 2 looks exactly like the 3rd fight the only difference Pac doesn't take risk anymore that's why no knock down & less mixed up but he did connect more although 1 or 2 at a time... JMM didn't dominate he just limit Pac's out put to his level so basically both of them are just answering punch per punch though JMM looks better because his style have that deceiving look. His punch looks connecting even though it's being block the difference would be people expected more on Pac so if he punch 1 or 2 at a time people perceived it as a defeat.
So, two punches were thrown in the whole round? Awful fight by the sound of things. Personally, I'd score it to A. The way I see it, boxer B got the better punch of the two, but all the control and pressure is coming from Boxer A as he is the one walking his opponent down.
