McGregor didn't throw any punches to defend himself during Mayweather's final series of punches, and they were crushing blows. McGregor's eyes rolled into the back of his head after one of those punches. They will always call that. People have died in the ring when they don't punch back. A lot of fighters are able to keep their legs while still getting their brain pounded. The refs won't chance it. They'll call it every time when a fighter isn't hitting back. McGregor knew that's how boxing worked. Either he was just being his ignorant self, or he was disoriented. He he lost the fight, by TKO, and it was the correct call. Period. People can cry conspiracy all they want to.
