Mike Tyson Vs Mohammed Ali (both when they were in their prime)
Muhammad was quoted as saying while at ring side for a Tyson fight when asked this very question that Tyson was no worse than Frazier.I think Muhammad especially before his ****** lay off due to refusing to be drafted would have boxed Tyson's ears off.
John McCain Vs Barack Obama,you can even make McCain 30 yrs younger.
