When she was asked on “Fighter vs. Writer” who she thinks has the best BJJ in the UFC, Dern didn’t hesitate to say it’s Charles Oliveira:

In my opinion the best jiu-jitsu in the UFC is Charles “Do Bronx”… Because of his Jiu-Jitsu in MMA.

In Jiu-Jitsu, he wasn’t a black belt world champion or ADCC world champion or anything. So, it wasn’t like in the Jiu-Jitsu world he’s the most famous guy; but in MMA, for me, he has the best Jiu-Jitsu in MMA.

[He has] the most submissions, knows how to play on his back, knows how to play on top.
If you want to know the best Jiu-Jitsu in MMA, [it’s] Charles “Do Bronx”.

She also mentioned that Gilbert Burns has the highest level of BJJ in MMA… But that Oliveira still has the best BJJ for MMA:

The best jiu-jitsu athlete that is in UFC now, that’s hard – but “Durinho” Gilbert Burns for sure.

His Jiu-Jitsu game, when we were in the Jiu-Jitsu world, people stopped to watch him fight.
World champion, ADCC, crazy – and he’s able to do that in MMA. A Jiu-Jitsu guy striking, he goes in, he’s not scared of getting punched and he has his takedowns and everything.

I think the most high-level Jiu-Jitsu guy in MMA now is Durinho. But the best Jiu-Jitsu for MMA, [it’s] Charles “Do Bronx”.
