Roy got huge wins against Hopkins[Both fighters first major title fight], Toney, McCallum in 93-96. Which IMO are the top 3 best wins of his career. Of course he has Gonzalez, Tarver, Ruiz, Hill, Harding, Griffin, Woods, Del Valle, Paz on his resume, but i'm just saying top 3. All i'm saying is, it's safe to actually say, who's the best fighter since the Whitaker and Jones era, not Whitaker alone. I just can't ignore Roy's wins over Hopkins, Toney and McCallum in the early-mid 90s.
So my answer is Floyd, B-Hop, Marquez. As the three best fighters since Whitaker and Jones.
