Longtime UFC commentator has sounded off this fighters’ struggle.

Fight fans have picked up on the factor that heavyweight title contender Francis Ngannou has a way of coming off as a monster when he competes in the Octagon.

However, once outside of the cage, he comes off completely different as he is quiet, soft-spoken, humble man.

As seen at the UFC 220 PPV (pay-per-view) event at TD Garden in Boston, Massachusetts on pay-per-view, UFC heavyweight champion Stipe Miocic successfully retained his title in the main event by scoring a dominant decision win over the title contender.

Ngannou was gassed after the first round and lost in a lopsided fashion. Following the fight, Ngannou made it known that this fight was a major learning experience for him.

If you recall, Ngannou officially earned the title shot after his bout when he picked up a first-round knockout of Alistair Overeem that left the veteran unconscious on the canvas for several minutes at UFC 218.

Miocic also defeated Overeem when he scored a first-round knockout over the longtime MMA star last year at UFC 203.

“He tried to take Stipe out in the first round. His thought was that Stipe’s not going to be able to survive,” Rogan said on a recent edition of his podcast (transcript courtesy of LowKickMMA). ”Stipe was a very good college wrestler and obviously a bad motherf****r.

He took some hard shots too but that’s the thing about Stipe. It’s not just that he knows how to fight, he’s just f*****g tough.

”I thought it’s very possible Francis could win this fight, he’s just so scary. I’ve never seen anyone that’s so terrifying with one punch.”

“You watch the training camps with Daniel Cormier, Luke Rockhold and Cain Velasquez, there’s a reason why those guys are so goddamn good because iron sharpens iron,” Rogan said.

“Those guys are in there, world champions going at it with each other on a daily basis and because of that, that’s what turned them into those f*****g monsters that they are today.

Francis is just a physical freak but if he was in that camp? Holy s**t. One camp in San Jose has some of the best fighters that have ever done the sport.” he added.
