Hopkins is the big problem. Whittaker, would be interesting to say the least. I have that a toss up so for the sake of argument I'll give it to him. Everybody else, his boxing ability wins it for him.
0-1 Assuming a fight with Hopkins is at 160 than Hopkins would win. Other than that he beats everyone else. That includes Whitaker at any weight.
were is the 0 poll. floyd would keep that 0. i have seen lower caliber fighters get wins over ike, hopkins, de la hoya and whitaker. so i now floyd could.
