Blachowicz ultimately won the contest via unanimous decision (49-46, 49-45 x2) — the large margin of victory baffling many punters.
It was a margin that had many people stunned about the result with social media backing Adesanya to have banked at least two rounds.
But the scorecard revealed that the fifth round, that was dominated by Blachowicz, went 10-8 to the Polish champ.
At the post-fight presser, White slammed the scoring, taking aim at a series of 10-8 rounds awarded.
"The scoring was insane, they're giving out 10-8's like..." he began. "There were two rounds in that fight that they gave as a 10-8. When I came up in the fight business, a 10-8 was an a** whooping. You got your a** whooped. You didn't do s*** in that round if it was a 10-8. This 10-8 s*** is out of control right now. So hopefully we can get this fixed. They're going to screw up a lot of fights if they're handing out 10-8s like that. There was no 10-8 in that fight."
He was asked about it again later and continued to slam the judges.
"I think we can all agree, that fight wasn't 4-1. That's bats*** nuts. If anyone watching that fight thinks it's 4-1, they're bats*** nuts, it was even going into the last round. And Israel was winning the first half of the round and then Jan took him down and won the fight in the second half of the round. The only thing that makes that 4-1 is ridiculous 10-8 rounds. It's a big problem with judging that needs to be fixed."
It was Adesanya's first defeat in the Octagon, the Kiwi failing to become the UFC's fifth simultaneous champion.
"It didn't go exactly the way I wanted it to go, I thought I'd win. But, you know, dare to be great," Adesanya said after the defeat. "I knew what to do but the size was a factor.
"I'm going back down to 185 and I'm going to rule that b**** with my iron black fist."
As for going up to the heavier division, fans were mixed about whether it was a good thing or not, with some taking aim at Adesanya, while other praised him for putting his unbeaten record on the line.
The ground work in the later rounds was all part of the plan for Blachowicz as he waited for the right time to pounce and put his weight to use.
"I thought he would be a little bit faster, but he hit harder than I thought," Blachowicz said.
"I knew that I was going to be better on the ground. I had to just wait for the good moment. He was a little bit tired so I waited for the good moment and tried to use it. If I would have knocked him out it would be better. But because he is one of the best of the world, I'm happy."
Former double-champ in lightweight and heavyweight Daniel Cormier said the weight difference was all that stopped Adesanya.
It comes after the New Zealander didn't add much weight to fight in the heavier division, while Blachowicz appeared to put on around 15 pounds between weigh in and fight time.
"When it comes to grappling, there's no substitution for size and technique," Cormier said. "It also shows going up 20 pounds is very difficult."
As for what's next in the lightweight division — it appears that Glover Teixeira is Blachowicz's next preferred contentder.
