Pereira is great. He saved that whole card. Whenever he wins or losses, he is entertainment. And I think he was more conservative with his crazy capoeira shit in that last fight than say Zabit, who is absolutely reckless and gasses in every third round. Pereira was quite fresh even by the end, seemed like he can go 5 rounds. (Of course he had mediocre opposition, a more active opponent or a wrestler that would go for a takedown may lead to different results.)
I hope they give him a top 10 opponent next time. It's not like WW is super deep anyhow.
