Looking back at Holmes victory over Rousey is a good example of what a boxer can do, once they develop the training of MMA and incorporated with their boxing ability. Throwing punches is one thing but a boxer has technique that goes beyond winging punches, which we seen in the Rousey fight. I think more good/great boxers should actually get into MMA. This is something I believe will pick up greatly as the future of MMA moves on. Holmes is stated as being the first to win a boxing title and a UFC title. I'm sure theirs a male boxer or upcoming boxer, who see this, and wants to do the same. Come out, come out where you are.
It's a good example of what any fighter/athlete can do if they commit themselves to a new discipline. Holly just still has the hunger because female boxing isn't anything big so she has to still work hard for her cash, not like Mercer or Toney who've had pay days and zero desire.
