Johnson is on an eight-fight winning streak which includes a 2013 title defense vs. Dodson that was one of the greatest UFC bouts of all time. Dodson brings the aggression and knockout threat, while Johnson's skill set is more well-rounded. Johnson has recorded 18 of his 22 wins by submission or decision, indicating stamina is key.

ESPN's Brett Okamoto noted that in his breakdown of this fight, where he gives Johnson the edge the longer the fight lasts.

"Early on, when Dodson had energy, he was explosive and mobile enough to keep that precious distance between himself and Johnson. As the fight went late, however, Dodson tired and Johnson's pressure slowly ate him alive," Okamoto wrote.

Dodson has won eight times by way of knockout, and stopped two of his last three opponents early. He is on a three-fight winning streak since dropping the 2012 decision to Johnson, and he will let his hands fly even more in the rematch.

"I missed the opportunity [of] knocking his head off," Dodson said. "I messed up with a few shots that I missed on, but I dropped him and I should have capitalized on it. I can admit that Demetrious was a tough opponent. So my opportunity is just to capitalize on every mistake that he makes."

Dodson has a victory over T.J. Dillashaw in his career, but he might take a lesson from him in this bout. Dillashaw's aggressive striking has carried him past Renan Barao, a superior technical fighter, twice.

Prediction: Johnson def. Dodson by UD.
