I am solid in my belief that the specificity of training done by a boxer doesn't produce a better striker than the all around training of a well trained MMA fighter. Iron Mike Benevides or Krazy Horse are examples of hard hitting talented strikers that would absolutely have a shot vs Mayweather.
We'll have to agree to disagree here.
I think he would win 12-0 against both. They'd have a tough time boxing with him, and a hard time hitting him with clean power shots. I think Mayweather v Krazy Horse would be a good MMA fight for Pretty Boy.
