While Overeem certainly wasn't given the same recovery time Browne had received moments earlier, the victor explained the difference in the scenarios: Overeem wasn't coming back.
"His eyes were so far back in his head that I wasn't even going throw a third hammerfist," Browne said. "I cocked back, but I was looking at him and thinking, 'Nah, he's done. I'm not going to hit him again.'
"There was no response from Alistair when he was flat on his back looking at the light. If he would have given him an extra five or 10 seconds, there would be something wrong with him right now. When your head is bouncing off the mat? The first one was the hardest one. I was actually landing on the ground when I threw it."
For Browne, who has lost just once in eight UFC appearances, the win helped to announce his arrival as a legitimate contender in the heavyweight division. How the stoppage affects his position in the public's eye remains to be seen, but Browne said he anticipated there would be a backlash even before he entered the cage.
"I almost called it before the fight even happened," Browne said. "I said, 'What's going to happen is I'm going to go out here, I'm going to win, and then everybody is going to make excuses for the guy.' I knew people were going to say, 'If he would have fought the Overeem back in the day, it would have been completely different.' I beat him. I knocked him out. Stop making excuses for the guy.
"When I sat in the press conference after I lost to Antonio Silva, I came out and said, 'I don't have any excuses. I lost the fight. You can't take that away from him.' People are going to make excuses for their favorite fighter or who they think should have won, but you have to look at the facts and see what happened."
Browne is certainly due for another big fight in his next contest. Fabricio Werdum is waiting on an opponent, and the winners of fights like Josh Barnett vs. Frank Mir, Daniel Cormier vs. Roy Nelson and even champ Cain Velasquez vs. Junior dos Santos will all be looking for a high-profile opponent.
While the 31-year-old Browne doesn't know what's coming next, he wants to put an end to any talk of what should or shouldn't have happened against Overeem.
"You get hit in the body, you're able to respond," Browne said. "I was responding the entire time. Yamasaki told me to do something, and I did it. He needed a sign of life, and I yelled at him. Yeah, you get kneed in the gut by Alistair Overeem, you're going to go down, and he's going to do his job of following up with those rabbit punches and try to finish the fight on a technicality. I didn't need the ref to finish the fight. He was out cold.
"This is a fight. Why do you need a ref to stop the fight anyway? He wasn't getting back up after I knocked him out. That's honesty. Alistair did everything he could do so he could win the fight in the first three minutes of the fight, but he would have needed the ref to stop the fight to get the win. I didn't need the ref to stop the fight. I stopped the fight.
