Gonzaga felt that he was too focused on striking during his last stint with the UFC and decided to refocus on his grappling for this bout.
Clearly the rededication did wonders for Gonzaga, as he was able to make very short work of Oliveira.
What we'll remember about this fight
Gonzaga's dominance on the ground.
Standing, neither fighter mounted much offense and it was a relatively even match, but once Gonzaga took the fight to the ground, it became quickly apparent who the more well-rounded fighter was.

What we learned about Gabriel Gonzaga:
He belongs in the UFC.
Gonzaga was once considered one of the top heavyweights on the planet and, although it's yet unclear whether he has returned to that form, it's evident that he at least deserves to be a part of the UFC's heavyweight division.
Oliveira is a tough up-and-coming fighter, who trains with heavyweight champion Junior Dos Santos, and Gonzaga was able to make quick work of him.
Based on that, he at least has what it takes to be a gatekeeper.
