Pyfer KO - Abus is more skilled and can hang with anyone for the first round but he fades so fast and consistently. It's not even the full first round, he has ~3 good minutes, then he starts mouth breathing and his movements become labored. Pyfer is also a gasser but he has 2 solid rounds, insane power, much more fast twitch, better chin, etc. I'm very confident that if it reaches the third round and it's close, Pyfer will have more left to push for the win/finish.
Ankalaev dec/ground and pound finish - Pereira is nowhere near as locked in these days. He's all about making money (which is fair enough). He's like Rocky when he becomes "civilized" and loses the fire. Meanwhile, Ank has never stopped grinding up in the mountains. Despite all of this, and the claims of a broken hand in the last fight, I think Pereira is simply an inferior MMA fighter. If Ank can land a takedown, I think he finishes the fight.
Zalal should win but odds aren't great. Also like Vanderford.
