I'd go with Hatton, the only way to get Vitali below 180lbs would be to cut off his arms and legs....
IDK, Vitali could come in looking like Manut Bol, but I think the catch wieght should be 174. More attainable for both.
You can be quite funny MM. But then you go and ruin it with stuff like "Is Hearns' power overrated?" I half expected you to follow that with "Was Ray Leonard the slowest and most overrated fighter of all time and would he even last 2 rounds with Khan or Ortiz?" If you could consistently mix humour and serious discussion,you would be onto something,but now we don't know half the time when you ARE kidding.
