That would be the equivalent of Floyd throwing a jab and his forearm snaps and starts flapping around. MMA is organized disorganized street fighting. Anybody can get in the ring. They even let Kimbo Slice get in.
The boxing equivalent would be someone throwing a punch and hitting the top of someone's cranium thus breaking their hand
thats what are you suppose to do in a street fight, the crown of the head is the hardest part of the body,
Chris Weidman did a good job with that, but I have a feeling Anderson probably been having problems with that leg anyway for other reasons which is why he had to take rest on his way to the ring
