Miocic captured the UFC heavyweight title with a one-punch knockout over Fabricio Werdum on Saturday at UFC 198, and while the UFC has yet to make an official announcement, Overeem remains the assumed No. 1 contender, having punched that ticket with a second-round knockout of Andrei Arlovski earlier this month.
The fight presents a fascinating stylistic match-up, one which pits Miocic's athleticism and boxing against Overeem's experience and vaunted kickboxing arsenal. However fellow heavyweight contender Junior dos Santos has tasted what both men have to offer inside the cage, and dos Santos believes if the fight between Miocic and Overeem gets booked, the belt is going to end up staying on the mantle of the new champion.
"If it happens, I'm going to give the advantage to Miocic again over Overeem," dos Santos predicted Monday on The MMA Hour. "I don't think Overeem has what it takes to beat Miocic. Miocic is really hard. Do you remember my fight against him, against Miocic? It was one of the toughest fights I've ever had. He hits very hard. He's got really heavy hands, so I think when I watch Miocic fight and Overeem fight, I think Miocic is way better than him."
Dos Santos is one of the few heavyweights to have fought both Miocic and Overeem. He captured a close unanimous decision over Miocic in 2014, but then fell to Overeem via second-round TKO in 2015.
That loss is still the crown jewel of Overeem's current climb to the top of the division -- a four-fight hot streak that also includes wins over Stefan Struve, Roy Nelson, and Arlovski -- and though Overeem has looked like a reborn fighter under the coaching staff at Jackson-Winkeljohn, dos Santos knows from personal experience that Miocic is a different breed of opponent than most heavyweights.
"[Overeem] did very well against a very tough guy, Arlovski," dos Santos said. "Actually, Overeem is coming from very good moments. He beat me, he beat Arlovski now, so he's doing very well. But like I said, I give the advantage to Miocic.
"But you never know. It's MMA. I'm sure Overeem has a lot of chances to be the next champion, but I think it's going to be hard for him."
Dos Santos admitted on Monday that his loss to Overeem is still the most difficult setback he's endured in his career. The two heavyweights were rivals for years, and losing in the way dos Santos did pushed the Brazilian's stock to the lowest it's been since his early days in the UFC.
But after righting his ship with a masterful victory over Ben Rothwell, dos Santos knows a second chance at avenging that loss is within reach as long as he keeps winning.
"That was something I have no words to explain, because that was hard," dos Santos said. "That was hard for me. I'm not saying that he's not good, that he doesn't deserve it. He deserved the victory. He won the fight. He was better than me. But man, even watching this fight now against Arlovski, sometimes I say ‘how did I lose to that guy?' But you know, I think it's part of the thing. I'm not being disrespectful to him. He's been fighting for a long, long time. But man, it would be great to have this rematch."
