Joe smith has a legitimate punchers chance. Unfortunately for him, Artur has a much bigger one in addition to being a far superior boxer. Beterbiev TKO 6.
The great thing about Smith Jr. is that while he usually is on the punchers chance side of things in big fights, he throws the kitchen sink in round 1. Very often we see guys who really only have a punchers chance try to box their way in and slowly have the steam taken out of them.
