Conor started throwing hammers and then Floyd turned his back and kept leaning. Conor kept falling for it. He's an idiot. He got played so hard. He was so fatigued he kept throwing punches, he was so aimed at winning by strength that he didn't realize Floyd was smiling his ass off the entire time. Then he gets dummied later because he literally can't keep his arms up anymore while Floyd is just "man, only the 8th round and I get free face shots?"
I mean ALL MMA fighters? ;-)
And Mayweather is really good at making people look like bafoons, or shutting them down.
