If Tenshin Nasukawa fought Floyd Mayweather in a MMA fight who wins this ?
A fight will always favor the fighter of the discipline of which rules are being enforced. A kickboxer vs a boxer in a regular boxing match the boxer wins. An mma fighter vs a boxer in an mma fight the mma fighter wins.
I didn't see any kicking. It was a seasoned pro boxer vs a debutant in a boxing match. The same as when he "fought" McGregor.
