You don't believe that he was acting? He was apparently more concussed than any fighter has ever been in the history of the UFC, even fighter's who have been brutally knocked out. When the doctor was going to allow him time to continue he turned up the acting and lay down on his back to make sure they stop the fight. He was absolutely acting more hurt than he was. It's understandable why he took the easy way out, he gets a win bonus and another title fight. But there is a reason guys like Anthony Smith get so much respect for NOT doing what Aljo did. It's clearly exaggerating an injury to take the easy way out and it's not a good look for the fans. The consequence of taking the easy way out is being called a coward for doing so.
