I would have to say Mayweather, Pacquiao, Marquez and Cotto. I know they havent all fought each other but if you could decide this generations fab 4 in the same weight class who would you pick?
the original fab four all fought each other. duran/leonard 1,2,3 leonard/hearns 1,2 leonard/duran hagler/duran hagler/hearns hagler/leonard floyd fought marquez and cotto....pac fought marquez and cotto... floyd didn't fight pac cotto hasn't fought marquez
The fab 4 have to have fought each other. This era's fab 4 is: Pacquiao, Barrera, Morales, and Marquez.
Alright, well for this question they dont have to have fought each person in it, one or two is good enough.
