People don't know how to score fights. Boxing is scored on clean punching, effective aggression and ring generalship. It's also scored on a round by round basis. In the first 5-6 rounds Alvarez won at least 4 of the rounds. After that he ran out of steam but he only needs to win 2 rounds to get a draw.
Many seem to be impressed with GGG taking 5-6 very clean punches walking forward and missing and hitting gloves with Alvarez backed up. In that scenario GGG loses the round as overly simplistic as I've made sound. Even if GGG lands but Alvarez rolls with the punches if Alvarez is landing cleaner and more flush, he's taking the round.
Also if Alvarez is throwing nothing and GGG is missing and hitting gloves for much of the round and then Alvarez lands very clean for 30 seconds then Alvarez has won that round because he's the one landing clean.
That said the 118-110 is a disgrace but a draw certainly isn't, neither is a close win for Alvarez.
Compubox is some random button bashers and it's a joke to think GGG was nearly as accurate by percentage as Alvarez. Does anyone actually believe that? Many of GGGs 'landed punches' were still hitting gloves or missing or not landing very cleanly. Whenever Alvarez threw he was landing very very clean for the most part.
