I will be adding clues as time allows.
Also I've labeled each one A, B, C & D.

I will also say that of the four, D is the hardest because he is a really unknown guy as far as recognition goes in the boxing world but when you look at what he did in his career. Your gonna be like WTF did this guy have to accomplish such things.

Cheers fellas.
