I don't know why people are giving Ankalaev a hard time. He was the busier, more aggressive fighter. Took more chances. Landed the only shot that actually hurt their opponent. Yeah he tied up Pereira for a few mins late in the fight, but aside from that, he was putting on a much more admirable performance than Pereira, and was the more "exciting" of the 2 fighters in this one. Didn't play it all that safe, had no problem exchanging. Alex did basically nothing but back up and throw leg kicks for 25 minutes besides a few fleeting moments.
The scoring system is the only way Poatan had a chance in this fight, because if you scored the bout as a whole Ankalaev clearly won. Pereira is way more guilty of making this fight boring than Ankalaev due to his backing up, lack of urgency and inability to get off the cage in round 4 and 5.
